Design And Analysis Of Large Span Steel Structure

Along with China’s economic take-off, people’s production and life constantly higher demands on the building space, including large-span building technology continues to develop. Compared to other building materials, steel materials with higher strength, ductility and toughness better, the material is more uniform, more in line with the assumptions when mechanical calculations, and the weight is small, easy to manufacture, easy construction and many other advantages, has been widespread used in modern large-span building structure design. Due to the form of large-span steel structure is complex, belonging to several statically indeterminate structure, the choice for the structure and mechanical analysis of large-span steel structure is still the focus of the study.This paper mainly from the following aspects:1、outlining the development of large-span steel structure, analyze the situation on the domestic and international studies of the structure and summarize the characteristics, structure, mechanical analysis and other aspects of the structure.2、and the combination of Hengshui University Gymnasium instance, the selection of the structure were discussed, with examples in this article, Hengshui Institute of Physical steel frame structure, the discussion of the structure, and introduces the structure calculation.3 、 using the finite element software MIDAS / GEN create a reasonable three-dimensional building models to calculate the single condition data.4、the structure at different load cases for static analysis, dynamic analysis, stability analysis, and analyze the performance of the anti-collapse of the structure.
