【摘要】 重庆江北嘴金融城2号项目结构体系较复杂,设计难点较多。对该项目结构设计过程中的若干问题进行了总结和阐述,比如超长地下室的楼板温度应力分析及针对性设计措施;抗震性能分析与设计;大跨度钢结构连廊的结构设计;大跨度钢结构连廊的舒适度分析和TMD减振设计;支撑连廊的钢骨混凝土大悬挑结构的分析与设计。设计中,针对以上难点采取了相应的措施,既满足了结构安全,也达到了建筑效果要求。更多还原

【Abstract】 The structural system of Chongqing Financial Center No.2 is complex,so the design is difficult.A number of issues during the process of structural design for this project were summarized and expatiated,as follows: the stress analysis of floor temperature for the super-long basement and related design measures,the analysis and design of seismic performance,the structural design of large-span steel corridor,the analysis of comfort level and the TMD damping design about the large-span steel corridor,the analysis and design of the big cantilever structure which was steel reinforced concrete and used to support the corridor.The measures for above mentioned difficulties were carried out during the design,and the results showed that the structure system not only met the requirements of the structural safety,but also reached the performance requirements of the building.更多还原
