【摘要】 杭州新天地办公楼采用框架-核心筒(双筒)结构体系,为不规则连体结构,结构平面规则性超限(扭转不规则)和立面规则性超限(双塔连体结构),在地震作用下结构反应复杂,扭转效应明显。运用ABAQUS软件建立结构三维力学模型,采用弹性时程法和弹塑性时程分析法进行地震反应计算,并针对相关抗震性能指标进行对比分析,以此考察结构的整体性能和薄弱部位。分析结果得出,本结构抗震性能良好,足以抵御6度地震。更多还原

【Abstract】 Hangzhou Xintiandi office building,which adopts structural system of frame-corewall(double tubes),is an irregular connected structure.The building is an out-of code structure with irregularity in plane(torsional irregularity) and in elevation(dual-towers connected building).The seismic response of the structure under earthquake action is complex with obvious torsional effect.The three-dimensional model of the structure was constructed using ABAQUS software and seismic response analysis calculation was carried out with elastic and elastic-plastic time-history analysis methods.The comparative analysis was executed aimed at related seismic performance targets to check the overall performance and weak parts.The analysis results indicate that the structure can undertake six degree earthquake effect due to good seismic performance.更多还原
