本文分析研究了高低跨厂房在地震作用下的结构反应。阐明了高低跨厂房的地震反应是平动——扭转相耦联的地震反应,并指出研究这一地震反应时,必须考虑地震对厂房的纵向作用和屋盖系统的剪切变形。本文从这个观点出发,建立了高低跨厂房的平扭耦联地震反应运动方程,推导出相应的计算公式,同时,对此进行了分析、讨论。
This paper analyzes and studies the structural response of high and low span factory buildings under earthquake. It is clarified that the seismic response of the high- and low-span buildings is a translation-torsional coupled seismic response. It is pointed out that when studying this earthquake response, the longitudinal effect of the earthquake on the building and the shear deformation of the roof system must be considered. From this point of view, this paper establishes the torsional coupled seismic response equations for high and low span buildings and derives corresponding calculation formulas. At the same time, it analyzes and discusses this.
