摘要
以合肥市某超高层框架-核心筒结构为例,对比分析两种设备层方案对总体结构的影响,采用PKPM及Midas Building软件进行小震下的弹性分析及大震下的弹塑性分析,并应用Abaqus软件对设备夹层剪力墙进行细部分析。计算结果表明:该框架-核心筒结构选取设备层作为单独结构层,能达到抗震性能目标确定的各项抗震性能要求,是安全、合理的。
Taking a super high-rise frame-core tube structure in Hefei as an example,the influences of two mechanical floor designs on the overall structure were compared.PKPM and Midas Building softwares were used to perform elastic analysis under small earthquake and elasto-plastic analysis under large earthquake.The Abaqus software was used to perform the detail analysis of the equipment sandwich shear wall.The calculation results show that this frame-core tube structure is safe as the mechanical floor is divided into a separate structure layer,which can achieve all seismic performance requirements of the Seismic Performance Objectives.
