摘要
本文对碗状悬伸结构的广州亚运会历史展览馆进行了罕遇地震下动力弹塑性分析,通过分析发现了支撑上部网壳结构的剪力墙筒受压损伤严重,以及悬挑梁塑性屈服,是结构的薄弱部位。优化分析表明,在混凝土剪力墙两侧设置钢板和增加连梁,可大大减少剪力墙筒的受压损伤,满足结构的抗震性能要求。
Asian Games historical exhibition Center in Guangzhou is a bowl shape suspension structure.The elastic -plastic dynamic analysis of its structure model under strong earthquake is carried out in this article.The analysis results show that the serious compressive damage shear-wall tube which supports the upper latticed shells and the plastic yield cantilevered beam are the weak parts of the structure.The optimization analysis shows that installing steel plate along two sides of concrete shear-wall and adding the coupling beam between two wall branches can significantly reduce the compressive damage of shear-wall tube and meet the requirements of the seismic performance.
