A Preliminary Study on Vibration Response of Profiled Steel Sheet Dry Board (PSSDB) System under Heel-drop Test

This paper aims to evaluate the vibration response of the profiled steel sheet dry board (PSSDB) composite system under heel-drop test. Three (3) specimens with dimensions of 840mm width and 2000mm length were prepared. The specimen consists of a sample without concrete infill (P45HL), foamed concrete as infill (P45FC), and normal concrete as infill (P45NC) material. The specimen was erected using profiled steel sheet (PSS), 1mm thickness, and connected to a dry board (DB), 16mm thickness using self-drilling screws at 200mm screw spacing along the longitudinal direction. A heel-drop test was conducted, and modal analysis was performed using MEscope software. The FRF measurement was carried out using accelerometers, and the time-domain measured responses were converted to FRF to acquire modal characteristics such as natural frequency and mode shape of the structures. The natural frequency of the first mode shape is 17.7Hz, 14.2Hz, and 4.5Hz respectively for specimen P45H, P45FC, and P45NC. It demonstrates that the natural frequency of the specimen without infill and foamed concrete as infill is more than the human comfort limit value of 8Hz, implying that P45HL and P45FC will be comfortable for building occupants.

Numerical investigation for the flexural load behaviour of profiled composite slab strengthened with CFRP

The profiled composite slab (PCS) is a composite structural system consisting of profiled steel sheet in-filled with concrete in the troughs and connected using studs. This system is a structural load bearing element. Lately, this system has been increasingly used as flooring or roofing structural element. The PCS has become as an extension or development to the most popular now a day's composite slab called profiled steel sheet dry board which was brought to the United Kingdom as an alternative to timber joist flooring for small span domestically buildings. Similarly, to other structural members, PCS demands strengthening and continuous upgrading due to many reasons like exposing to accidents or to improve its ability to bear an extra load. There are a quite limited studies related to the improvement of the PCS strength thus, this study suggests investigating the effect of using carbon fiber reinforced polymer (CFRP) plates to strength the PCS and enhance its ability to carry an extra load. Three parametric studies were considered in this study, the effect of thickness, length and location of the CFRP plates on the flexural load behaviour. The FE analysis results, proved that using CFRP as a strengthen technique for the PCS system has a positive effect on the ultimate flexural bearing capacity which increased by 16.5%, 29.5% and 41.0% using different CFRP plate thickness (1.5, 3.0, and 4.5 mm, respectively). Moreover, when different CFRP plates length (1000, 1500 and 2000 mm) were used the ultimate flexural bearing capacity raised up to 4.0%, 10.0% and 16.5% respectively while the amount of increment were 16.5% and 39.0% when using different CFRP number of sheets (2 and 4 sheets respectively). Lastly, this study strongly recommends using CFRP sheets as a strengthen technique for the PCS system.

Experimental and analytical investigation on shear behavior of profiled steel sheet dry board composite wall system

Profiled steel sheet dry board (PSSDB) composite wall/panel system with advantages (like lightweight, enhanced flexibility, low-cost, simple pre-fabrication/erection process, no temporary formwork requirement etc.) is an innovative construction technology that has significant potential to be used as a viable alternative to its conventional counterparts in earthquake prone region. No significant research study is available on the structural behavior of PSSDB composite walls under in-plane shear loading. Nineteen PSSDB panels consisted of single profiled steel sheet (PSS) assembled with single or double plywood dry board (DB) are tested under shear loading to failure. The effects of boundary frame, central opening, concrete in-fill, fastener orientation, and panel geometry on load-deformation response, strength and failure modes are investigated and compared. Analytical models for shear capacities of PSSDB composite system of various configurations are developed based on modified code-based/existing equations and their performance validated using experimental results. These analytical models can be used by engineers in designing PSSDB composite system for practical construction.

The two-way flexural performance of the PSSDB floor system with infill material

This paper investigates the structural performance of the Profiled Steel Sheeting Dry Board (PSSDB) system; a lightweight composite structure which is made by binding a Profiled Steel Sheeting (PSS) to a Dry Board (DB) by mechanical screws. Many studies indicated that it can be used as flooring units. However, most of them focused on utilizing the system as a one-way floor panel. It's rare to find studies that consider the two-way position, and so far none has ever considered the effect of the infill material in that situation. Therefore, the purpose of this paper is to investigate the flexural performance of the two-way PSSDB floor panel with the presence of the infill material. An Experimental (EXP) and Finite Element (FE) approaches were employed. For the EXP tests, it was found that applying a steel plate (SP) can enhance the stiffness and strength of the PSSDB system by approximately 31% and 15%. The results were used to compare with the ones of a previous study, and it was shown that applying infill material can improve the strength by 13.2%. Applying both Steel Plate (SP) and infill material instead of SP alone can enhance it by 13.6%. As for the FE approach, it was demonstrated that changing the thickness of the DB and SP has a minor effect by no more than 5%, while changing the PSS's thickness can affect the performance by up to 18.3%. And finally, the effect of changing the type of infill material is less than 1%.

Theoretical and finite element analysis of the two-way PSSDB floor system

The profiled steel sheet dry board (PSSDB) system is a lightweight composite structure which consists of profiled steel sheeting connected to dry board by self- tapping and self-drilling screws. It can be used as flooring, walling and roofing panels. This paper presents the investigation of the two-way flexural behavior of the PSSDB floor system. The study employs both theoretical and non-linear finite element (FE) analysis. The FE approach has been done using ABAQUS software. While the theoretical one was conducted using an elastic full interaction analysis. The obtained results were verified against experimental tests and it was shown that both the theoretical and FE solutions are adequate enough to predict the behavior of PSSDB system. After that, several parametric studies have been conducted to have a better comprehension of the factors that affect the behavior of the system. It was found that the changing the dry board depth can enhance the behavior up to 23%. However changing the type of board has a minor effect on the elastic stage and it starts increasing in the plastic period up to 14%. Also, it was shown that changing the thickness of steel sheeting can affect the performance by approximately 18%. Screw spacing has an impact on the strength of the system up to 9.6%. Finally, applying line load has demonstrated a better two-way action than point load.

Experimental Test and Non-Linear Finite Element Modeling Prediction on Profiled Steel Sheeting Dry Board (PSSDB) with Geopolymer Concrete Infill

Profiled steel sheeting dry board (PSSDB) system is made of profiled steel sheeting that is connected to the dry board using a self-drilling, self-tapping screw. This study aims to predicts the load-deflection behavior of PSSDB panel system under the influence of geopolymer concrete infill with finite element modeling. To achieve the target objective, the laboratory testing approach and a theoretical system behavior prediction are considered. Through a bending test, the stiffness of PSSDB full board with geopolymer concrete infill (FBGPC) panel is 27.42 kNm2 and the ultimate load is 13.13 kN/m2. The developed finite-element modeling (FEM) successfully predicts the behavior of PSSDB with geopolymer concrete infill panel with >85% accuracy.

Effect of Geopolymer Concrete Infill on Profiled Steel Sheeting Half Dry Board (PSSHDB) Floor System Subjected to Bending Moment

Profiled Steel sheeting Dry Board (PSSDB) system is a lightweight composite structural system consisting of profiled steel sheeting, mechanically connected to a dry board using self-drilling and self-tapping screw. The objective of this study is to investigate the effect of geopolymer concrete infill in PSSDB system with half board (PSSHDB), focus on its deflection serviceability limit at mid-span region. Geopolymer concrete was chosen to be as infill in the PSSDB floor system due to its high compressive strength as compared to normal concrete and its potential as an alternative concrete since it does not utilize Ordinary Portland Cement (OPC). This study used a modified PSSHDB panel using a half-sized dry board. In achieving this objective, forecasting the behavior of the system in laboratory experiments will be taken into account as the research approach. Experimental results found that with the use of geopolymer concrete infill, the mid-span deflection on the PSSHDB floor system can be reduced to 41% as compared to the use of normal concrete infill. This indicates an increase in the stiffness of this system due to the effect of infill geopolymer concrete.

Comparative Study Floor Flexural Behavior of Profiled Steel Sheeting Dry Board between Normal Concrete and Geopolymer Concrete In-Filled

This study investigates the behavior of in-filled materials of profiled steel sheeting dry board (PSSDB) floor system. Two tests were conducted, namely, push-out test to know the connection stiffness and bending test on the PSSDB panel under the influence of different in-filled materials. Result of the push-out test shows that the connection stiffness of the geopolymer concrete-filled PSSDB is 331% higher than that of PSSDB that is filled with normal concrete. This connection stiffness contributed to the reduction of deflection value of 21% in the middle of the midspan for full-board geopolymer concrete in-filled panel bending test. This phenomenon triggered the increase of interaction within the composite system, making the panel that is filled with the geopolymer concrete 25% stronger than the normal concrete–filled panel.

Non-linear analysis of membrane action effect in profiled steel sheeting dry board flooring system

This study highlights the effect of membrane action in improving load carrying capacity of Profiled Steel Sheeting Dry Board (PSSDB) floor system. PSSDB system is a lightweight composite structural system composed of profiled steel sheeting and dry board, attached together by self-drilling and self-tapping screws. Many literatures have reported that restricting conventional slabs, such as reinforced concrete slab, at the supports against translation and/or rotation while it is subjected to vertical loading develops the compressive membrane action in the slab. The development of this phenomenon is considered in the PSSDB system with concrete infill for continuous and practical spans, with and without topping concrete. Previous authors’ experimentally verified non-linear finite element model for the PSSDB floor without topping was extended to parametrically predict the effect of different boundary conditions on the performance of the system for practical applications. It was revealed that preventing the in-plane movement of the slab ends improves the flexural rigidities of the slab up to more than three times when considering central deflection of serviceability limit state. This was observed when the deflection limit load of the fixed both end supports model was compared to the pin-roller support model. Moreover, the topping concrete enhances the applicability of the system in longer span and the developed compressive membrane action dramatically boosts the load carrying capacity of the slab with restricted translation and/or rotation of the slab ends.

Experimental Evaluation of Profiled Steel Sheet Dry Board Wall Panel System

This research paper describes the investigation of new innovative form of lightweight composite known as Profiled Steel Sheeting Dry Board (PSSDB) wall panel system. Profiled Steel Sheeting Dry Board (PSSDB) is categorized as Industrialized Building System where paneling system has been developed to substitute the traditional structure of brick wall. The proposed system is a novel form of double and single sheathed composite panel. It consists of dry board and profiled steel sheet for middle core, attached by screws at both surfaces forming the composite action. This paper present the experimental results of twelve full scaled samples of PSSDB wall panel by using Cliplock 610 and PEVA45 as profiled steel sheet and PrimaFlex dry board for surface sheathed. All 12 wall panel samples have been tested under axial load until failure. From the experiment, it was found that the maximum load capacity of PSSDB wall panel can withstand is 1329kN with PEVA45 at screw spacing of 200 mm. While for the wall panel assembled using Cliplock 610, the maximum load is 612kN. The study shows that the new PSSDB wall panel system has a great potential to be used as a load bearing under axial load and expected to have a confidence for structural system in future construction.

This study examines the effect of different variables of Profiled Steel Sheet (PSS) on various aspects of Profiled Steel Sheet Dry Board (PSSDB) system. PSS is an important component of PSSDB. The sensitivity of PSS variables at the 70% to 140% of Peva45 dimensions, the profiled steel sheet at local markets, to the cross-sectional area of PSS, the ultimate load carrying capacity, and the flexural stiffness of the PSSDB system is analysed. Results are shown in charts, and the most effective variables are determined. The dominant variables are found by saving computational time in the optimization of PSS in the PSSDB system.

Dynamic response of low frequency Profiled Steel Sheet Dry Board (PSSDB) floor system

Slender structural floors could experience irritating vibration problems due to human walking load and so, vibration acceptability of such floors is an essential subject in addition to the usual strength criterion. This paper focuses on the dynamic response of a lightweight composite structural system known as Profiled Steel Sheet Dry Board (PSSDB) to evaluate its vibration acceptability under human walking load. For this point, twelve (12) PSSDB panels in the category of Low Frequency Floor (LFF) were developed via Finite Element Method (FEM). The natural frequencies and mode shapes of the studied panels were determined based on the developed finite element models. For more realistic evaluation on dynamic response of the panels, dynamic load models representing human walking load were considered based on their Fundamental Natural Frequency (FNF), and also time and space description. The peak accelerations of the studied panels were determined and then compared to the limiting value proposed by the standard code of ISO 2631-2. Effects of changing thickness of the Profiled Steel Sheet (PSS) and Dry Board (DB), screw spacing, damping ratio, type of support, and floor span on the dynamic responses of the PSSDB panels were evaluated. According to literature, effect of presence of concrete on the dynamic response of the PSSDB system was revealed. The results demonstrated that although some factors reduced dynamic response of the PSSDB system under human walking load, low frequency PSSDB floor system could reach high vibration levels resulting in lack of comfortableness for users.

The effect of profiled steel sheet's cross section on the strength-to-weight ratio of profiled steel sheet dry board floor system: A parametric study

Composite system of Profiled Steel Sheet Dry Board (PSSDB) is a system composed of profiled steel sheet (PSS) and dry board (DB), attached together by self-tapping or self- drilling screws. PSS, the most significant structural component of this system is currently sourced from the available profiles in local markets. Yet, it is apparent that manufacturing specific PSS for this system can result in a more economical system. This paper investigates the effect of varying cross-sections of PSS on the PSSDB system regarding ultimate load carrying capacity (strength) and (weight) of the system.

Profiled Steel Sheet Dry Board (PSSDB) composite panel has been proven to be an effective structural system and can be exploited for a variety of structural purposes. As a flooring system, the PSSDB floor carries the out of plane bending and shear mainly in the direction of corrugation of profiled steel sheeting. For such flooring system, human induced vibrations are becoming increasingly vital serviceability and safety issues. In this paper, investigations are carried out on the vibration performances of the PSSDB floor panel. This research is focused mainly on the fundamental frequency of such floor panel. The influence of various board types, board thickness, and connectors spacing on fundamental frequency are evaluated. It was shown that for all the panels considered in this paper, the fundamental frequency was well above 8 Hz and hence, this type of composite floor panel will not be uncomfortable to the occupants of building in terms of vibration.

This paper investigates the dynamic response of a composite structural system known as Profiled Steel Sheet Dry Board with Concrete infill (PSSDBC) to evaluate its vibration serviceability under human walking load. For this point, thirteen (13) PSSDBC panels in the category of Low Frequency Floor (LFF) were developed using Finite Element Method (FEM).

Effects of changing thickness of the Profiled Steel Sheet (PSS), Dry Board (DB), screw spacing, grade of concrete, damping ratio, type of support, and floor span on the dynamic responses of the PSSDBC panels were assessed. Results demonstrated that although some factors reduced dynamic response of the PSSDBC system under human walking load, low frequency PSSDBC floor system could reach high vibration levels resulting in lack of comfortableness for users.

Experimental Study on the Compressive Membrane Action in Profiled Steel Sheet Dry Board (PSSDB) Floor System

This paper describes the experimental work conducted at Universiti Kebangsaan Malaysia to examine the capability of the profiled steel sheet dry board (PSSDB) system to develop the compressive membrane action (CMA) in the floor. The development of the CMA inside the floor is strictly associated with the horizontal movement of the slab end under the vertical loading. Therefore, the simply supported PSSDB floor was tested under vertical uniformly distributed load. Study of results revealed that the recorded horizontal movement at the roller support of the slab is 0.81 mm in the pin- roller supported case. This proves that the PSSDB floor has the potential to develop the CMA under the pin-pin support condition.

In a wide numerical study, the FNF of the PSSDBC system with practical dimensions is revealed for different lengths, widths, and boundary conditions. The results help designer predict serviceability and design criteria of the studied panels.

This paper describe the experimental performance of Profiled Steel Sheet Dry Board system (PSSDB) against out-of plane bending and vibration. The PSSDB panel consists of plywood attached to the top surface of profiled steel sheet by self-drilling and self-tapping screws. Profiled steel sheet dry board panel has been used successfully as flooring system in few construction projects within Malaysia. As a lightweight flooring system, human induced vibration is becoming increasingly vital serviceability and safety issues for such panel when it is covering relatively longer span or area. Therefore, it is important to evaluate the factors affecting the structural performance and also to consider the effects of vibration in building such flooring system. This paper will focus on theoretical and experimental procedures to determine the overall performance of PSSDB system due to flexural bending and vibration. Each parameter that effect the perfonnance of PSSDB system against vibration and flexural will be discussed in this paper. It is found that PSSDB panel with a practical span length have a natural frequency well above of 8Hz and hence, considered comfortable to the occupants of building in teens of vibration.

The Effect of Butt Joint on the Structural Behaviour of PSSDB Wall Panel

An experimental investigation was carried out to determine the effect of butt joint on the structural behaviour of profiled steel sheet dry board (PSSDB) load bearing wall with window opening. The samples tested were three (3) PSSDB walls with window opening and butt joint in the dry boards, and three (3) PSSDB walls with window opening but without butt joint in the dry boards. The samples were subjected to axial compressive load and comparisons were made between the two sets of samples. The average value of the ultimate load capacity for PSSDB load bearing wall with butt joint was found to be 286 kN, while that for the samples of PSSDB load bearing wall without butt joint was 260 kN. The average maximum lateral deflection values for both types of PSSDB walls were 8.9 mm and 13 mm respectively. Significant difference due to butt joint in dry board was seen in the reduced number of cracks by about 33 % in comparison to that without butt joint.

Finite element prediction on the structural performance of profiled steel sheet dry board structural composite system proposed as a disaster relief shelter

Folded plate structures constructed from profiled steel sheeting connected to dry boards by self drilling, self tapping screws (known as profiled steel sheeting dry board (PSSDB) system) are being proposed as an alternative to traditional forms of roof construction. The proposed load bearing composite structural system consists of an assembly of individual PSSDB panels connected by steel angle plates at the ridges, formed to the required shape, width and span. This kind of structure has a significant advantage of removing the internal trussing and support that is normally required in a traditional trussed roof system, thus adding to livable space in a building. The introduction of this innovative system would eliminate the difficulty in constructing folded plate roof that is normally very troublesome, especially when they are made out of traditional reinforced concrete system, hence would help promote the folded plate technique of construction. This paper looks into the possibility of employing the PSSDB folded plate structure to provide an efficient emergency shelter, analysing it under the effect of static wind loading using the already established and verified Finite Element technique. Such a structure is quite conceivable in the likely event of a disaster. Firstly, its basic behaviour in the elastic range is studied checking for deflection as the main controlling design factor. Secondly, the method of enhancing the structural stiffness and performance of the system is proposed. It was found that this could be easily achieved by restraining the bottom longitudinal edges on both sides of the structure. A practical solution is proposed in this paper that can be implemented in real practice. It can be concluded that the proposed structure has a great potential to be exploited for the above-intended purpose.
