摘要
考虑框架剪力墙结构与筏板-桩-土之间共同作用的影响,用ANSYS对一20层框架剪力墙结构以及筏板-桩-土建立整体空间模型;着重分析了桩-地基土对上部结构动力特性的影响情况,包括结构振型、周期、位移、内力等动力特性及地震反应行为;并与刚性地基基础假定情况下的结构计算结果进行了分析比较,得出一些有用结论,供工程设计时参考。
The cooperative effects of the tall frame-shear wall structure-piles-soil system are considered,and a 3D model of a 20-floor structure is established by using the software ANSYS. The effects of the piles-soil system on the dynamic properties of the structure are analyzed with regard to vibration modes, vibration periods, displacements, internal forces and earthquake responses. The results are compared with those of the structure on rigid foundation. Some useful conclusions are obtained.
