摘要
以合肥某超高层带裙房结构的东北角角柱不能落地情况为例,采用多种数值模拟方法对带斜撑的混凝土转换桁架结构抗震性能展开研究。在多遇地震下,分别采用SATWE程序对整体结构弹性分析和ABAQUS有限元软件对转换桁架区域隔离体弹性分析;在罕遇地震下,采用MidasBuilding软件分别对整体结构进行了静力弹塑性分析和动力弹塑性时程分析。结果表明:转换桁架对主体结构的侧移刚度影响有限,混凝土转换桁架在没有内置型钢的情况下可满足工程使用安全。
In the case of a super high-rise building with a podium in Hefei,whose the northeast corner column cannot be grounded,various numerical simulation methods were employed to study the seismic performance of a concrete transfer truss structure with braces.For the frequent seismic condition,the SATWE program was used for the elastic analysis of the overall structure,and the ABAQUS finite element software for the elastic analysis of the isolated bodies in the transfer truss area.For the rare seismic condition,the Midas Building software was utilized to perform both static elasto-plastic analysis and dynamic elastoplastic time-history analysis of the en⁃tire structure.The studies indicate that the transfer truss has limited impact on the lateral stiffness of the main structure.The concrete transfer truss,without built-in steel profiles,can meet safety requirements for engineering applications.
