(北京三磊建筑設(shè)計有限公司，北京100048)[摘要] 寧夏萬豪大廈位于銀川市，銀川市地處8度抗震設(shè)防區(qū)，地震分組為第二組。萬豪大廈主體結(jié)構(gòu)是一棟50層的復(fù)雜超高層建筑，主體高度200m。本文利用PERFORM-3D對該超限高層建筑結(jié)構(gòu)進行動力彈塑性時程分析，得到結(jié)構(gòu)在罕遇地震作用下的變形和力學性能，對結(jié)構(gòu)在大震作用下的整體反應(yīng)和構(gòu)件損傷情況進行了分析和評估，驗證了結(jié)構(gòu)在大震作用下大震不倒的性能目標。

( Beijing Sunlay Design Group Co., Ltd., Beijing 100048, China)Abstract: Marriott building is located in Yinchuan, and Yinchuan is located in 8 degree seismic fortification areas for the second earthquake group. The main structure is a 50-story super high-rise complex building, the lugh of main body is 200m. The paper obtain the deformation and mechanical properties with PERFORM-3D by using Structure dynamic elastic-plastic time history analysis, evaluates the overall reaction and component damage of the structure under the rare earthquake and validates the structures perform objective of standing upright in rare earthquake.
Keywords: super high-rise buildings; dynamic elastic-plastic; seismic performance; oblique column switching; rhombic core wall
