摘要
重庆西永综保区监管大楼办公主楼为大跨度连体结构,连接体跨度为58.6m,连接体底部与顶部均采用钢结构桁架与两侧的筒体相连形成巨型框架。通过对比分析确定了钢桁架的结构方案,按抗震性能化设计的概念进行结构设计;采用SAP2000软件进行了弹塑性时程分析,分析了连接体桁架及筒体的受力性能;并通过振动台试验和节点试验验证了结构及节点连接的可靠性,并在计算分析及试验结果的基础上采取了相应的抗震加强措施。
The Regulatory Building in Chongqing Xiyong Integrated Free Trade Zone is a large-span connected structure with the connected body of 58. 6m. Steel trusses set in bottom and top of the connected body connect with the tubes at two sides to form a mega frame. The structure scheme of steel trusses was determined through comparative analyses,and the structure was designed according to the concept of performance-based seismic design. The software SAP2000 was used to carry out the elasto-plastic time-history analysis and analysis on the mechanical properties of the steel trusses and tube structure. By shaking table tests and joint tests,the reliability of the structure and joint connections were verified. Relevant seismic strengthening measures were taken based on the calculation analyses and experimental results.
