Research of Construction and Incorporate Design of a New Cooperative Grids Composed of Prestressed Cables and Chord Members
Based on the analysis of application and development of the prestressed steel structures and the pretressed grids especially of the world, A new structure which is gather the pretressed grids and suspended structures’s characteristics and which is formed......
 
Analysis on Elastic-plastic Seismic Response of the Long-span Truss String Structure
The long-span truss string structure is one of the new long-span pre-stressed steel structure in recent years, which has been widely used in many national and foreign engineering practices and has revealed good prospects. Aseismatic capability of these pu......
 
Optimal Design of Pre-Stressed Steel Structures by Improved Genetic Algorithms
Pre-stressed steel structure is a novel structural system and has been widely used in all kinds of buildings such as bridge, factory workshop, sport building and so on. The theory of its optimal design has yet to be solved in the follow aspects: Optimal d......
 
Study of Assemble Pre-stressed Pre-fabricated Structure
The development of the space structure has two requirements. One is to enlarge the application scope of the space structure and the other is to decrease the expenses of the structure. One of the approaches to resolve this problem is to reseach on and impr......
 
Research on Fire Response and Performance-based Fire Resistant Design of Pre-stressed Suspended Lattice Shells
It is known that strength of steel material reduces significantly under high temperature in fire. For pre-stressed structure system, the pre-stress relaxation of steel cables with high strength in high temperature is likely to cause structural collapse. T......
