高烈度区火电厂钢结构主厂房选型研究
|
摘要
结合抗震设防烈度为9度的某火电厂房钢结构主厂房的结构选型,采用振型反应谱分解法和静力弹塑性分析方法对框架-中心支撑方案和框架-偏心支撑方案进行抗震性能和结构延性的比较研究,并进一步对其经济性进行了对比。结果表明:9度区钢结构主厂房框架-偏心支撑体系具有更优越的抗震性能和经济性。
Combined with the steel structure selection of main power house in the 9 degree seismic intensity region,a comparative study of the seismic behavior and ductility for centrically braced frame structure and eccentrically braced frame structure by using modal response spectrum decomposition method and Pushover analysis method was conducted and compared in terms of the economy of the two structural type. The results showed that eccentrically braced frame structure had superior seismic performance and its economy would be demonstrated in the 9 degree seismic intensity region.
