兰州理工大学体育馆的整体分析与计算

目前,国内许多展览场馆及体育馆采用上部网架,下部混凝土框架的结构形式。由于设计软件的不足,一般将上、下部结构分别建模进行分析计算,与整体计算相比误差较大。以兰州理工大学体育馆为工程背景,从水平地震作用、温度应力以及整体稳定极限承载力等几个方面对结构进行整体分析计算,并与分别建模计算结果进行对比分析。结果表明,由此带来的计算误差不可忽略,并在该结果基础上提出设计建议和对策。

GLOBAL ANALYSIS ON FLAT GRID STRUCTURE GYMNASIUM

At present, many exhibition halls and gymnasiums have been built. The substructure of these buildings is concrete frame and the superstructure is flat grid. Because of the design software’s shortage, normally flat grid and concrete frame was individual analyzed. In this paper, taking the Lanzhou University of Science and Technology Gymnasium as the project background, global analysis of the gymnasium from these aspects： earthquake load, temperature stress and the elastic-plastic stability bearing capacity was caried out. At last, the results with the individual analysis results was compared. The calculation error of two methods should not be ignored and based on the results, the design recommendations was proposed.
