摘　　要：该项目中结构存在扭转不规则、楼板不连续、组合平面不规则、框架柱局部托柱转换等不规则项,针对工程特点和规则性超限情况,对整体结构采取了相应的计算分析措施和抗震加强措施,并采用了抗震性能化设计。通过多遇地震作用下反应谱分析和弹性时程分析、设防地震和罕遇地震作用下关键构件承载力的等效弹性验算及罕遇地震作用下动力弹塑性时程分析,表明结构及关键构件均能满足设定的抗震性能目标要求。同时对楼盖的温度应力和典型楼板在设防地震下的承载力进行了补充验算,对局部穿层柱进行设防地震下的稳定验算。There are some irregularities in the structure of the project,such as torsion irregularity,floor discontinuity,combination plane irregularity,partial column transformation of frame column,etc.According to the characteristics of the project and the regularity beyond limit,the corresponding calculation and analysis measures and seismic strengthening measures are taken for the whole structure,and the seismic performance design is adopted.Through response spectrum analysis and elastic time history analysis under frequent earthquakes,equivalent elastic checking calculation of bearing capacities of key components under fortification and rare earthquakes,and dynamic elastic-plastic time history analysis under rare earthquakes,it is shown that the structure and key components can meet the set seismic performance targets.At the same time,the temperature stress of the floor and the bearing capacity of the typical floor under fortification earthquake are checked,and the stability of the local through-layer column under fortification earthquake is checked.
