摘　　要：为研究某左右不对称灯泡贯流式厂房结构在静动力荷载作用下的位移、应力分布规律,采用三维有限元动力反应谱法对其进行抗震分析,计算中采用完全二次项组合(CQC)法考虑双向的扭转耦联作用,应用Westergaard公式考虑地震动水压力。结果表明,该厂房位移应力分布合理,可为同类工程提供参考。In order to study the distribution laws of stress and displacement of bulb tubular power house with left- right asymmetry struction under the action of static and dynamic loads, three-dimensional finite element dynamic response spectrum method is used to aseismic analysis of the power house. Considering the bidirectional torsional coupling action, the complete quadratic combination （CQC） method is adopted and the seismic dynamic water pressure is calculated by using Westergaard formula. The results show that the distributions of stress and displacement of the power house are reasonable, which can be referenced by the similar projects.
