[摘要] 西安浐灞凯宾斯基酒店建筑外形呈螺旋式上升，建筑平面由底部旋转贯穿至顶部，总旋转角度达450，建筑立面先收后扩，给结构设计带来很大难度。采用SATWE和ETABS有限元程序对结构在多遇地震下结构的抗震性能进行了分析，同时采用非线性有限元软件PERFORM-3D对结构进行静力弹塑性补充计算和采用OPENSEES对斜柱进行计算分析。分析结果表明，该结构体系是安全、可行的。

Abstract: The architectural shape of Kempinski Hotel Xi'an Chanba is upward spiral, and the building plane is rotated from the bottom to the top of the rotation with the total rotation angle of 450. Building facades, which first income then to expansion, posed a big problem for structural design. The seisnuc behavior of structure was analyzed by SATWE and ETABS. While using non-linear finite element software PERFORM-3D and OPENSEES, the additional calculation of push-over and the analysis of inclined column were given respectively. The results show that the structural system is safe and feasible.
