［摘要］以光明新区公共服务平台工程为例，详细探讨了基于PERFORM-3D的弹塑性模型的建立及动力分析中一些常见问题的解决方法；选取了3组地震波，考虑三向地震作用分析结构的弹塑性时程反应，得到结构在罕遇地震作用下的变形、内力和损伤情况。分析结果表明：结构分析模型准确可靠；少量钢筋混凝土梁进入弯曲塑性状态，但未达到弯曲破坏状态，连梁未发生剪切破坏；部分剪力墙混凝土拉、压应力较大，少量延性屈服；转换构件均处于弹性；层间位移角小于1/100；结构满足罕遇地震作用下性能水准的要求。

Abstract: Taking Guangming New District public service platform as example, a series of common problems and solutions about the establishment of PERFORM-3D based elasto-plastic model and dynamic analysis were studied in detail. Three groups of earthquake waves were selected. Three-direction rare earthquake induced deformation, deformation, internal forces and damage status were obtained by analyzing structural elasto-plastic time-history response. Results show that: analysis model is accurate and reliable; a few reinforced concrete beams reach bending plastic status but do not reach bending failure status, and no coupling beam reaches shearing failure status; tension and compression stress of concrete of some shear wall is large, and a few of them ductile yield; transfer members are in elastic status; inter-story displacement angle is less than 1/100; the structure meets the requirements of performance levels under the rare earthquake.

Keywords: large-span arch-transfer structure; performance level; elasto-plastic time-history analysis
