［摘要］8度区某高层酒店，地下1层，地上13层，结构高度58-9m。因工程原有结构方案超出规范规定的最大适用高度，需对方案进行修改并采取有效的加强措施。针对该高层较为复杂的建筑特性，从抗震性能与经济性角度出发，在框架-剪力墙、钢支撑-混凝土框架及钢支撑-框剪结构方案中进行对比分析，最终选择钢支撑框剪结构作为结构设计方案，从而使得该工程具有良好的结构性能，同时有效解决了结构的超限问题。

Abstract:A high-rise hotel in eight seismic degree area has structural height of 58-9m, and it has 13 floors over ground and 1 floor underground. Because the  height  of original structure is larger than the maximum suitable height specified by code, it is necessary to revise the scheme and take effective measures to strengthen the structure. Considering the complex features of the high-rise building and the mechanical performance and economic efficiency of the structure, three schemes were compared and analyzed, including frame-shear wall structure, steel braced concrete frame structure and steel braced frame-shear wall structure. The steel braced frame-shear wall structure was chosen as the final scheme, which made the project had better structural performance and effectively solved the out-of-code problem of the structure.

Keywords:high-rise building; frame-shear wall structure; steel braced concrete frame structure; steel braced frame-shear wall structure; seismic performance analysis; scheme comparison
