摘要
郑州国家干线公路物流港综合楼工程为复杂连体高层建筑结构。本文进行了结构在小震作用下的弹性分析,以及中震、大震作用下的弹塑性计算分析。介绍了设计过程中针对工程超限情况及复杂性因素所采取的结构措施,以及关键部位和重要构件的性能设计目标。分析结果表明,设计中采取的措施有效控制了结构在地震作用下的不利响应,结构动力弹塑性分析对关键部位的结构构件提出了有效的设计措施,优化了结构设计,满足了提出的性能化设计目标。
The project is a complex tall building with connecting structure on the upper level. The elastic analysis under frequent earthquakes and the elastoplastic analysis under medium and rare earthquakes are performed. This paper describes the structural measures in view of the instances, which are beyond seismic fortification and of complexities, during the design, and the performance objects for crucial members and significant parts. Suggestions based on the elastoplastic analysis are also proposed. The results show that the unfavorable responses of structure under earthquakes are effectively controlled by the structure measures adopted, the structure design is optimized and the performance objects are fulfilled.
