摘要
汕头苏宁电器广场结构总高99.5 m,是大底盘双塔高层结构体系,2个塔楼均采用钢筋混凝土框架-核心筒结构。采用PKPM软件对结构进行多遇地震作用下的弹性时程分析以及罕遇地震作用下的弹塑性动力分析,选择了和规范反应谱吻合良好的地震波,探讨了结构最大位移、层间位移、基底剪力、塑性铰分布等抗震性能指标,为结构设计和结构抗震性能评估提供了重要依据和参考。
A total height of the structure of the Shantou Suning Appliance Square is 99.5 m.It is a two-tower high-rise structural system.Both towers adopt reinforced concrete frame-core tube structure.The PKPM software is used to analyze the elastic time history of the structure under multiple earthquakes and the elastoplastic dynamic analysis under rare earthquakes.The seismic waves with good spectral response are selected.The maximum displacement,interlayer displacement,base shear force and plastic hinge distribution of the structure are discussed.The results provide an important basis and reference for structural design and structural seismic performance evaluation.
