[摘要]空中華西村存在超高、多塔連體及頂部收進(jìn)等多項超限,地震響應(yīng)復(fù)雜,在常遇地震和設(shè)防烈度地震作用分析的基礎(chǔ)上,采用ABAQUS進(jìn)行罕遇地震動力彈塑性時程分析,通過輸入地震波,研究結(jié)構(gòu)的非線性響應(yīng)過程。計算結(jié)果顯示:結(jié)構(gòu)上部、特別是頸部筒體是整個結(jié)構(gòu)的薄弱部位,屋面樓板及頸部筒體混凝土在地震中出現(xiàn)明顯損傷,屋面徑向連體附近局部鋼梁達(dá)到屈服。根據(jù)以上結(jié)果,提出了增加頸部筒體厚度、頸部剪力墻配置型鋼框架和約束邊緣構(gòu)件、優(yōu)化屋面結(jié)構(gòu)布置等加強(qiáng)措施,保證頸部筒體罕遇地震下不屈服。

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
