摘要

以某火力发电厂主厂房为原型,建立整体结构的空间计算模型,对其分别进行模态分析和水平双向地震作用下的弹塑性时程分析。结合拟动力和伪静力试验研究,探讨框排架结构的空间变形性能及塑性铰的分布特点。针对此类结构特点引起的严重地震扭转效应,提出减小扭转的措施,改善了火力发电厂主厂房在高烈度地震作用下的动力性能,为工程设计提供参考依据。
Based on the prototype of main building in a thermal power plant,the spatial computational model of integral structure was established.Modal analysis and elasto-plastic time history analysis under two-directional horizontal earthquake were carried out.Combined with the former quasi-dynamic experiment and pseudo-static experiment,the spatial deformation performance and plastic hinges distribution were studied.At last,the torsional controlling measures against the serious torsional response induced by the structural features were pointed out which can be used as reference to engineering design and the dynamic performance of main building in thermal power plants would be enhanced.
