[摘要]空中华西村存在超高、多塔连体及顶部收进等多项超限,地震响应复杂,在常遇地震和设防烈度地震作用分析的基础上,采用ABAQUS进行罕遇地震动力弹塑性时程分析,通过输入地震波,研究结构的非线性响应过程。计算结果显示:结构上部、特别是颈部筒体是整个结构的薄弱部位,屋面楼板及颈部筒体混凝土在地震中出现明显损伤,屋面径向连体附近局部钢梁达到屈服。根据以上结果,提出了增加颈部筒体厚度、颈部剪力墙配置型钢框架和约束边缘构件、优化屋面结构布置等加强措施,保证颈部筒体罕遇地震下不屈服。

Abstract:Kongzhong Huaxicun is an ultra-limit high-rise building and the seismic response is complex. Based on the analysis under frequent and occasional earthquake, elastic-plastic time history analysis with ABAQUS software is carried out and the nonlinear response of the structure under earthquake wave is rescarched. It is shown that the cetral tube in the neck area is the weak part. The concrete of the roof slab and shear wall in the neck area are damaged, and some steel beams near radial connections yield. Based on the analysis of the structure, some design instructions are proposed to strengthen the weak parts and to ensure unyielding.
Keywords:high\|rise building; elastic-plastic time history analysis; aseismic performance; ABAQUS
