摘要
长江生态环境学院图书馆造型特殊,底部为无柱大空间,上部结构最大跨度41.4 m,并存在16.8 m的悬挑。经结构方案对比分析,采用了钢框架-中心支撑-悬挂结构体系。对结构进行了小震、中震、大震作用下的分析计算,结合可能的施工方案,进行了施工模拟分析。计算结果表明,结构可以达到预定的抗震性能目标,在计算分析的基础上采取相应的抗震加强措施,其结构方案及分析方法可供同类项目参考。
The Library of Yangtze River Institute of Ecology and Environment has a special shape,with a large space without columns at the bottom,a maximum span of 41.4m and a 16.8 m overhang on the upper structure.The steel frame-central brace-suspension structure system is adopted by comparing and analyzing the structural schemes.The analysis and calculation of the structure under the action of small earthquake,moderate earthquake and large earthquake,combined with the possible construction scheme,the construction simulation analysis is carried out on the basis of calculation and analysis,the corresponding seismic strengthening measures are taken,and the structural scheme and analysis method can be referenced.
