［摘要］北京财源国际中心西塔楼为35层，结构总高度154.8m。工程采用型钢混凝土框架加钢筋混凝土核心筒结构体系，并在层26设置了加强层桁架提高结构的抗侧刚度。按抗震设防超限审查意见，对工程采取控制底部墙体剪压比不大于0.15，小震作用下框架承担的剪力不应小于层剪力的25%，伸臂桁架由12榀减为4榀等构造措施，使结构抗震性能有了可靠的保障，对于顶部9层的偏置核心筒的抗震设计也取得了较好的效果。

Abstract:West Tower of Beijing IFC. is a super-high structure which has 35 floors with 154.8m total structural height. The structural system is formed by steel-concrete frame and core reinforced concrete wall.There is a strengthening floor in the 26th floor.The structural seismic performance is ensured by selecting seismic fortification measures with the opinion of experts for seismic design.The seismic design of 9 floors on the building top with remoted center core wall has a good design.
Keywords:composite structure; strengthening truss; remoted center core wall; seismic examine
