Large-Span Cable Stayed Structure Performance Analysis

With the 2008 Beijing Olympic Games will be held as well as cultural, sports, industrial production continuous develop, the inter-space steel structure are universal in China. High-strength alloy materials and the extensive application of high and new technology, increasing the weight of the structure more light and the span of the structure growing, people enhance the performance of large-span space structure of demand, thus contributing to the large-span space in the structure of China's rapid development.Stay Cable of Prestressed Steel Structure is the new hybrid structure of cable hybrid structures. Cable-stayed collaboration system, the earliest dating back to the bridge structure in the application of the load-bearing rope bridge, and the housing structure of the mid-20th century began. It has reasonable force performance, good economic returns and the beautiful architectural modeling, enriching the system of large space structures and it is a sign in high-tech construction technology.In this paper, with the Shanghai Automotive Hall of cases, I mainly research and analysis on the following four aspects.(1) through the project structure of the geometric composition and morphologided research, discuss the Stay Cable of Prestressed Steel Structure 's concept of design.(2) finite element based on the Stay Cable of Prestressed Steel Structure through non-linear features of the structural system,I use of finite element software in the structure INCLUDINGthe five kinds of single status and five kinds of adverse conditions under the combination of internal forces and anti-bearing deformation The calculation and analysis of the results, given the cable-stayed structure of Rafah hanging by the deformation of the(3) the establishment of two finite element model, calculated before the 10-band frequency and type, and the results were compared to the suspension of the upper structure(4) in theory and design specifications on the basis of Stay Cable of Prestressed Steel Structure, response to the earthquake impact analysis, and analysis of pre-tension cable layout and optimize the results of the impact.The way of analysis is built on the theory and practical work in close connection with the analysis made on the basis of the results of more anastomosis the actual work status. In this paper, the conclusion of the works have a certain value, finite element software simulation results show that the subject of calculation used in the process is effective, further study at the same time as cable truss structure to lay the foundation.
