摘　　要：某双塔楼超高层结构总高度为186.3m,因平面超长产生较大的扭转效应,进而影响整个结构的抗震性能。通过设置防震缝,将其分成B级、超B级高度的两个超限高层,采用钢筋混凝土框架-核心筒结构。根据结构动力弹塑性时程计算分析,并融入性能化设计思想,采取必要的加强措施,同时,通过1∶30比例振动台试验进行验证,确保整个结构满足"中震可修、大震不倒"的抗震设防目标。The total height of the twin towers high-rise structure is 186.3m, due to the super long plane and large torsional effects, the seismic performance of the whole structure will be affected. By setting the seismic joints, the building was divided into two high-rise structures with Class B, super Class B respectively. Reinforced concrete frame-core wall structure was adopted. According to the structural dynamic elastic-plastic time-history analysis, performance-based design, strengthening seismic fortification measures for necessary, and shaking table test on 1 ： 30 model, the whole building can be ensured to meet the ＂moderate seismic fortification goal of repair, not collapse under rare earthquake＂.
