摘要
针对钢筋混凝土横向框排架、纵向框架-剪力墙结构的某火力发电厂主厂房,提出在水平地震作用下结构的空间整体计算模型,进行平扭耦联的空间地震反应分析,以研究该类结构的动力特性。在三种地震波输入下,计算结构的层位移、层间变形及层剪力,对比平面模型和空间模型的计算差别,提出结构的空间作用比及考虑扭转作用的空间工作调整系数;得出对于偏心不规则结构,不考虑空间扭转效应的设计是不安全的,获得了具有实用价值和理论意义的成果。
It is proposed an integral model to analyze the seismic response of a large-scale thermal power plant＇ s main building with frame-bent in the transverse direction and frame-shear wall in the longitudinal direction under three certain seismic waves. The following subjects are concerned： the space model, the dynamic properties, the layer displacement, the interlayer deformation and layer shear, and compared the calculation result of the plant model with space model. The spatial effect ratio and adjusting coefficient of space structure were suggested, and the spatial effect was very obvious. Designing of the eccentric and irregular space structure was not safety without considering of the spatial effect of torsion on the structure. The valuable and theoretical achievements have been yielded.
