A PROPOSAL FOR SEISMIC VULNERABILITY ASSESSMENT OF PRE-ENGINEERED STEEL BUILDINGS IN BANGLADESH USING SIMPLIFIED JAPANESE INDEX METHOD

At present seismic evaluation of structures has become very crucial in Bangladesh as the country is in earthquake prone region. Lots of studies have been performed and many methods have been proposed for the rapid seismic evaluation of reinforced concrete (RC) buildings. Over the past two decades the country has been going through an important evolution which is rapid construction of pre-engineered steel buildings (PEB). Unfortunately, there has not been a single research work done or any method proposed for the seismic evaluation of these type of structures. In this work, simplified structural evaluation which is based on Japanese Index Method has been used for the seismic evaluation of 05 existing PEB steel structure. The structural seismic index of the building, IBS has been compared with the seismic judgement index IBSO which is a function of seismic zone co-efficient, structural importance coefficient and normalized acceleration response spectrum. The service load index IBD has also been compared with service load judgement indices, IBD01 and IBD02 which has been calculated from the material strength. For example, from the judgement of one building at ground floor, 0.5IBSO ≦ IBS＜IBSO and IBD02＜IBDhave been observed hence immediate detail evaluation recommended.

Performance and protection of pre-engineered buildings subjected to blast and earthquake excitations

A pre-engineered building (PEB) refers to a building which is pre-designed at a factory using some simulation and modelling software as per the specifications, codes and the loads that act on the structure before the production of the building components and then finally assembled at site thereby reducing the completion time. In the current study, a case study of an existing PEB structure subjected to wind analysis has been investigated. The main objective of the present study is to evaluate the retrofitting ability of passive control dampers installed in the pre-engineered industrial building subjected to earthquake and blast phenomenon. The study investigates the effectiveness of vibration control techniques in the form of passive dampers in improving the performance of PEB structure subjected to blast and earthquake using fluid viscous dampers. The study also discusses the impact of different damper placement techniques on the structural performance of PEB structure subjected to blast and earthquake loading. Primarily three damper placement techniques are incorporated in the present study, namely single diagonal, V-shaped damper, and inverted V-shaped damper. The study also evaluates the optimum fluid damper properties, namely damping coefficient and damping exponent, in mitigating the blast and earthquake responses of the selected industrial building. The structural performance of PEB structure has been studied using finite element tool considering the nonlinear analysis and comparing the structural responses for with and without damper conditions. The V-shaped and inverted V-shaped damper placement techniques are the most effective approach in resisting the damaging effects against blasts and earthquakes for the selected PEB structure in comparison with the conventional diagonal braced dampers. The study reports reductions in structural displacements and brace forces in the range of 54–68% and 70–90%, respectively, when installed with V-shaped fluid viscous damper.

Structural analysis and design for a warehouse using STAAD PRO

Aim of this study is to brief about the pre-engineered buildings systems proposed for Warehouse Building. The need for steel building increased lot recently, due to its ease, faster construction and weight by strength ratio than concrete structures.

A Collateral study on Optimization of Pre-Engineered building with Tubular sectional connection

Over the recent years, innumerable upheaval has been done in the field of steel construction industry, out of which pre-Engineered buildings (PEB) are one of the most remarkable ones. Pre-Engineered buildings are typical steel structures which are pre-fabricated and the designs are pre-determined which are contemplated to be more cost efficient, because of the tapered sections being utilized, in accordance with its bending moment requirement. These types of structures will not only be cost effective and environmentally friendly but also more flexible, thus eradicating the failure due to sequel of seismic forces. PEBs are generally industrial structures, which are designed for enormous spans. In this research work, the variation of structural behaviour of PEBs when it’s been embraced with considerably increased spans (30 m, 60 m and 90m) are compared and studied. In general, hot rolled tapered I-sections are used in erection of a PEB. Due to the inadequacy in connection configurations available, Pre- Engineered light weight cold form steel structures with tubular steel sectional connections are not well renowned. An attempt is also been made to bring out tubular sectional connections for the beam- rafter junction in all the PEBs deigned for 30 m, 60 m and 90m using E350 steel. Typical connections are proposed for both main frames and the gable frames of the PEB. The outcome of this study appears to be contended for at both the junctions in 30 m span and 60 m span, but 90 m main joint fails, due to the substantial bending moments developed across the major axis. So, these set of connections can be adopted for PEBs up to a moderate span, which helps in reducing the weight of steel that is been utilized in the construction, which successively foster sustainability.

A state of art review on analysis and design of pre-engineered buildings

Construction of steel buildings is increasing very rapidly due to its strength, flexibility, recyclable nature, longer span, no limitation in size of components and more seismic resistance capacity as compared to concrete buildings. A Pre-Engineered Building (PEB) refers to a building which is engineered at a factory as per the specifications, codes and the loads that will be acting on the structure before production of the building components and then finally assembled at site thereby reducing the completion time. The concept of PEB involves predesigning and prefabrication process. The material usage in PEB is optimized by matching the frame geometry with the bending moment diagram’s shape, which reduces the overall weight of the structure. In the present study, a review on the analysis and design of PEB structure is presented. The study discusses the various components of the PEB system and provides a detailed step to model PEB structures. From the past studies, it has been found that PEB structures are up to 50% lighter due to the usage of tapered I-sections and cold formed “Z” & “C” sections, approximately 35% cheaper as compared to the conventional steel structures and show reduced lateral and vertical displacements when subjected to the seismic loading and can be constructed in half the time taken for conventional steel buildings (CSB). PEB gives a better output from the architectural point of view with large clear spans & flexibility in future expansion. It has also been found that construction of PEB is more sustainable, environment friendly and economical than CSB.11Corresponding Author.
