摘　　要：对某火电厂主厂房中钢筋混凝土框排架结构进行了空间地震反应分析,研究了该类结构的动力特性、层间变形及扭转效应、框架与排架内力分配等相关内容,可供服役期该类结构可靠性鉴定及加固参照。The seismic response of a large-scale thermal power plant＇ s main building which takes three-dimensional effect into account is analyzed. The seismic wave whose peak acceleration takes 50gal is inputted. The following subjects are concerned： the dynamic properties, the effect of torsion on the structure, the interlayer deformation and torsion effect. It provides a valuable reference to reliabilities identity and reinforce.
