国能福建生产指挥中心项目不规则结构设计分析

Analysis of Irregular Structure Design for Fujian Production Command Center of CHN ENERGY

介绍了国家能源集团福建生产指挥中心的结构设计情况。通过抗震性能化设计、楼板应力分析和楼板舒适度分析等方法,解决了结构设计中跃层柱、楼板不连续、尺寸突变和大跨度楼盖等结构不规则难点问题。同时补充进行了多遇地震作用下的弹性时程分析和罕遇地震作用下的弹塑性时程分析,确保了结构设计的安全可靠。

This article introduced the structural design analysis of an office building with structural irregularity.By using methods such as seismic performance-based design,floor stress analysis,and floor comfort analysis,difficulties of structural irregularity in structural design such as cross story columns,discontinuities in floor slabs,size mutation and large-span floors have been solved.At the same time,elastic time history analysis under frequent earthquakes and elastic-plastic time history analysis under rare earthquakes were supplemented to ensure the safety and reliability of structural design.
