Data Analysis on Safety Monitoring of Group Pile Foundation Based on Valuation Fusion Algorithm

The transfer mechanism of super-large deep-water pile group foundation is quite complex, the traditional design and construction technology has been unable to meet building requirements while the applications of new technologies and new processes are lacking technical support. At present, the informatization in whole construction process basing on safety monitoring is an effective way to solve the problem. To ensure the safety monitoring system to work properly, the sensors are often redundant layout. however, the redundant data would cause data inconsistency and even contradiction. In order to eliminate this contradiction and to have the real force characteristics of pile group foundation, the valuation fusion algorithm was used in mult-sensors data fusion analysis. The result shows that the axial force and deformation of pile group foundation meet true response better after fusion.

Analysis of Building Technology on WANGYUE Pavilion of Golden Phoenix Temple

The Pavilion structure, as a perfect blend of beauty, practicability and flexibility, is widely adopted in Chinese classical gardens. Besides, pavilions about which a plenty of poems and tales have been made are so delicate, mysterious and gorgeous that they are usually very ideal places for recreation. Focusing on the renowned WANGYUE Pavilion of Golden Phoenix Temple, this paper aims at studying the construction technologies on double-eaves pavilions of timber structure used in Qing dynasty, by means of site survey and other investigating approaches. According to the investigation, the typical and traditional construction technology in south China on double-eaves pavilions was adopted, and the octagonal pavilion with double eaves and pyramidal roof was completed mainly using three beam-erection approaches such as the method of corner beam in the horizontal direction, the method of girder and the method of lever. This pavilion, as a representative structure with reasonable loading form, is constructed in good agreement with local culture and environment, which can provide certain valuable references for the design and construction of antique pavilions nowadays.

Design and Field Measurement Analysis of Steel Template in Axis Rotating Structures

The template system, the mould of fresh concrete, plays an important role in the concrete structure construction. At present, in the process of steel template concreting in axis rotating structures, the template system adopts the traditional construction technology of formwork with scaffolding; thus, the template can not withstand the loop force, hence difficult construction and safety hazards. Aimed at the deficiencies in template system design, a new kind of steel template that can bear loop force has been designed with the software ANSYS. Taking a rotating structure as an example, this paper, based on the stress test of the structure, has analyzed the distribution and change of the stress under the steel template construction. The results show that the design of the template is reasonable and that it is also applicable to similar structures.

Nonlinear dynamic analysis of fiber reinforced ultra-long span cable stayed bridges

The central span, which is the most critical part of a cable-stayed bridge, has almost reached the technical limit for traditional materials, construction technology and bridge system capability. The idea of Ultra-long Span Cable Stayed Bridge (USCSB) is proposed in this paper by introducing a hybrid type cable stayed bridge as a competent system. The new system leads to huge reduction in deck weight and critical stresses in the pylon zones by using a hybrid advanced composite deck. A multi-scale modeling technique is adapted which represents material design at the micro/macro-level, and accurate homogenization of the advanced composite components properties and evaluation of the resulting anisotropic characteristics. The dynamic performance under wind and seismic excitations, and the potential deficiency of such a bridge system is investigated via state-of-the-art computer simulations and large-scale dual shaking table experiments. The investigation result demonstrated that adopting a fiber reinforced polymer deck system can efficiently reduce internal deck stresses due to the high strength of FRP materials and the tubular type of lay-up structural system, increase its load carrying capacity of cable stayed bridges and hence, have a great potential extent the span length of stay cable supported bridge system. At the same time, due to the relatively low Young's modulus and shear modulus of fibrous materials, deflection at full loading and torsional resistance should be carefully controlled by using a convex initial configuration with sufficient internal bracing. Moreover, investigation results also suggested that wind induced coupling excitation is likely to occur in such a light-weighted system with low shear and torsional stiffness.

Restoration of Wandu Mountain City Palace

First built in A.D. 198, Wandu Mountain City, which lies 2.5 kilometers north to Ji’an City of Jilin Province, was the site of the once important capital of early-middle Koguryǒ. In this article, we creatively reconstruct a group of palace complex on Wandu Mountain City by combining the survey of the present remains and the analysis of archaeological excavation report and previous research findings with traditional architectural theory and construction technology. Based on the analysis of the characteristics of different parts of the palace remains, the article elaborates the determination of the reconstruction date of the Wandu Mountain City Palace, provides grounds for reconstruction design and reconstructs the whole architectural complex on the four stylobates.

Computing as Reflected in the Technology Roadmap for Center for Technology Fusion

We see the rapidly increasing trend of traditional construction technologies being merged with other advanced technologies, such as information, bio-, and nanotechnologies. A consensus has already been formed that one of the most effective research strategies is to break down the walls between divisions and departments so that people with different expertise can come together to cooperate. Simply put, to meet the new challenges that our society will bring, civil engineers have to learn, use, and research what is being studied and developed outside of the traditional realm of civil engineering. In September 2005, with the support of the Korea Ministry of Construction and Transportation KMOCT , the Center for Technology Fusion C4TF was established to promote multidisciplinary research for the significant advancement of construction industry practices. Technology fusion means truly significant interdisciplinary research. One of the main goals of C4TF is to develop research programs that can improve the productivity and safety performance of construction projects throughout their entire life cycle. To this end, C4TF made a substantial effort to understand 1. How our day-to-day lives will change in the future; 2. Present and future construction industry market needs; and 3. Ultimately what research programs we need to effectively prepare for the future. C4TF carefully reviewed more than 1,500 academic papers, approximately 2,000 patents, and existing research programs and policies all around the world that are related to our endeavor. We conducted a series of panel discussions, questionnaire-based surveys, and seminars to obtain the opinions of a large number of experts with diverse backgrounds. After almost 2 years, we have identified 30 research programs as the most important objectives of C4TF. This editorial presents the 25 that are most closely related to computing. Each program has detailed explanations about its research needs and objectives, the technologies to be developed, the estimated cost for research, and a technology development roadmap for that program for the next 5 to 10 years. However, for efficient

From “Opus Craticium” to the “Chicago Frame”: Earthquake-Resistant Traditional Construction*

Earthquake-resistant traditional construction? One may consider the phrase to be an oxymoron, but there are many examples of traditional construction that have fared well in large earthquakes. This finding is certainly important for historic preservation efforts because the analysis and documentation of this phenomenon can bolster attempts to preserve the fabric of historical structures. There is, however, an even more powerful lesson to be learned from these historic structures — a lesson on how to improve new construction. This point is crucial because in recent earthquakes in diverse parts of the globe it is the modern buildings that often have proved to be most fatal. This finding is also of importance for historic preservation because vernacular buildings that are only admired for their appearance — and not for their traditional construction technology — will never be preserved in a manner that properly protects and reveals their true cultural value. This article will explore examples of timber-laced non-engineered masonry construction that have proven to be comparatively resistant to earthquake damage and discuss the reasons why they have proved more robust than what might be expected.

Use of the GTAW method for surface hardening of cast-iron

Technologies which make it possible to improve the working properties of surface layers of castings, while utilising traditional materials, are increasingly being used in industrial applications. The life of fabrications can be extended as necessary. It is also possible to manufacture fabricates with working properties that are normally unobtainable in the case of traditional construction materials and technology.
