采用 NosaCAD、PERFORM-3D 和 ABAQUS 三种有限元软件对重庆某剧院空间复杂结构进行弹塑性时程分析，研究该结构在6度多遇和罕遇地震作用下的抗震性能。通过顶点位移、层间位移角、基底剪力等指标考察结构的整体反应，比较了不同软件计算得到的结构损伤情况。分析结果表明：多遇地震作用下，结构构件未出现损坏；罕遇地震作用下，主要结构构件损坏顺序和损坏分布较为合理且能在一定程度上耗散地震波输入能量，整体结构可以满足“小震不坏，大震不倒”的设防要求，分析结果对评价结构的可靠性有一定意义。

To study seismic behaviors of a complex theater building structure in Chongqing,China,under frequent and rare intensity of 6 degree earthquakes,elasto-plastic time history analyses were performed by using NosaCAD,Perform-3D,and ABAQUS.Structural responses,such as nodal displacement,story drift, and base shear obtained from different software were compared. Results show that, under frequent earthquakes,the structure has no damage.Under rare earthquakes,the damage distribution on main structural components are reasonable,which indicates that the structure has a good energy dissipation.The design satisfies code requirements of no damage under frequent earthquakes and no collapse under rare earthquakes.
