赛得大厦属现代化高层办公楼,由南北塔楼及高位连体钢结构桁架组成。详细介绍了结构体系的设计要点,重点分析了高位连体桁架与塔楼的连接方式、铅芯橡胶支座的数值模拟;基于性能化设计采用罕遇地震作用下弹塑性时程分析对结构抗震性能进行评价。分析结果表明,在地震作用下结构能够满足预期的抗震性能目标,同时,通过罕遇地震作用下弹塑性时程分析找出了结构的薄弱部位,并采取相应的抗震加强措施。 Sai Tak Building is a modern high-rise office building, which is composed of the north-south tower and the tall steel truss. The key points of the design of the structure system are introduced in detail, and the connection mode of the high-level integral truss and the tower and the numerical simulation of the lead rubber bearing are analyzed emphatically. Based on the performance-based design, the elasto-plastic time history analysis Evaluation. The results show that the structure can meet the expected seismic performance under the earthquake and the weak parts of the structure are found through the elasto-plastic time-history analysis under rare earthquakes, and the corresponding seismic strengthening measures are taken.
