Integral Analysis of Steel Space Grid Roof and RC Sub-frame/Wu Yongjun, Zhen Qinghua (The Architectural Design and Research Institute of Guangdong Province, Guangzhou 510010, China)
Abstract: The gymnasium of Guangzhou University of Traditional Chinese Medicine, which locates in Guangzhou University Town, is a long-span space structure. Using the FEM program STAAD, the analysis of spectrum, elastic time-history analysis and temperature effect are all applied in the integral model consisting of the steel roof structure and RC sub-frame. These ways simulate really the mixed-structure and analyze integrally the seismic performance and interaction between the roof structure and RC sub-frame. Based on the analysis, the evaluation of the work capability of the integral structure is presented.
Keywords:space grid; long-span space structure; elastic time-history analysis; integral analysis
