摘要
本工程存在4项不规则情况,结构抗震性能目标取为C~D级。采用2个不同力学模型分析软件YJK4.1.1及ETABS2018进行多遇地震作用下的结构整体计算,对楼板大开洞区域进行楼板应力分析。采用YJK软件进行结构罕遇地震下的弹塑性进行时程分析,根据分析结果对结构薄弱位置采取加强措施。
There are 4 irregularities in this project,the structure performance objective is grade C~D.Two software are used to calculate the structure under frequent earthquakes,slab stress analysis is carried out for the large opening floor.YJK software is used to carry out the elastic-plastic time-history analysis under rare earthquakes,strengthening measures are taken for the weak position of structure according to analysis results.
