摘要
重庆来福士广场项目的一个重要设计挑战是空中连桥结构设计与其高位连接方案。系统阐述了空中连桥结构体系及其分析设计方法,并讨论了不同连接方式对结构性能的影响,最终创新地提出了高位连体的减隔震设计方案。对不同设计工况,应用不同的分析模型和假设,以抗震性能化设计为根本,对空中连桥的结构性能、隔震层以及支承节点的地震表现进行全面的评估。在配合建筑与机电等其他专业的同时,满足了结构经济性要求。
One of important design challenges in Chongqing Raffles City project is sky bridge structural design and its connection scheme in high level. The structural system and its design and analysis methodology were systematically described,with discussing the impacts on structural performance due to different connection approaches. The seismic isolation scheme in high level is innovatively adopted to the final design. Under the conditions of various load cases,the different models and assumptions were implemented. A full assessment on sky bridge' s structural performance,seismic isolation,and its connection was conducted in terms of performance based seismic design. By co-operating with architecture,MEP and other disciplines,the structural economy index is fulfilled.
