ANALYSIS OF MECHANICAL PROPERTIES FOR LARGE-SPAN STEEL STRUCTURE DURING DIFFERENT CONSTRUCTION PROCESS

摘要

The chief aim of the present work is to investigate the influence of structure during the different construction process. The construction mechanics combines structure mechanics and construction technology together, and it is the product which combines traditional mechanics with the civil engineering. This is a working theory which is based on the idea that the finite element method. With the development of society and technology, the largescale span structures have been used a lot in our country. However, the large-span steel structure is generally designed on the basis of the whole structure, and the influence of structure during the different construction process is not considered by the designers. With the project of world University sports center, three different construction processes are discussed in this paper. The research we have done suggests that construction process is one of the important impacts in the complicated structures and the "path effect" can not be neglected for the complex large-span steel structures. The discussion on these problems provides basis for reasonable construction.
