【摘要】 郑州国际金贸港为三塔连体超限高层,根据各塔平面布置非轴对称的特点,确定两个连接体分别采用刚性连接和柔性连接的方案;针对结构的超限内容,设定合理的抗震性能设计目标;采用两种软件对结构进行多遇地震弹性计算及弹性时程分析;对结构的关键构件进行设防地震、罕遇地震等效弹性分析;对三塔连体结构进行罕遇地震动力弹塑性时程分析,揭示结构薄弱部位,评价结构整体的承载力能力和变形能力;对连接体关键节点进行应力分析;对连接体的楼板进行罕遇地震下抗剪承载力验算;根据计算结果提出相应的抗震加强措施。更多还原

【Abstract】 Zhengzhou International Jinmao Port is a three-tower conjoined over-limit high-rise building, according to the non-axisymmetrical characteristics of the plane layout of each tower, the two connecting bodies to adopt the scheme of rigid connection and flexible connection respectively; Set reasonable design goals for seismic performance in view of the over-limit content of the structure; Two kinds of software are used to carry out elastic calculation and elastic time history analysis of the structure in frequent earthquakes; Perform equivalent elastic analysis of fortified earthquakes and rare earthquakes on key components of the structure; Perform dynamic elasto-plastic time history analysis of the three-tower conjoined structure, reveal the weak parts of the structure, and evaluate the overall bearing capacity and deformation capacity of the structure; Stress analysis on key nodes of the connecting body; Check the shear bearing capacity of the floor slab of the connection body under rare earthquakes; Propose corresponding seismic strengthening measures based on the calculation results.更多还原
