本文分析研究了单层等高刚度分布非对称的厂房(简称单层偏心厂房),在地震作用下屋盖变形对平动-扭转耦联反应的影响,建立了计算模型,推导出各基本计算公式,据此编制了电算程序进行大量的计算和对比分析,指出在一般情况下屋盖变形的影响是不容忽略的,并给出考虑屋盖变形时进行地震反应分析和计算的简化方法。本文还分析探讨了地震转动分量的影响,估算方法和扭转反应谱的合理性,研究结果表明:目前采用的估算方法和有关文献给出的扭转反应谱都严重夸大地震转动分量的作用。
This paper analyzes and studies the influence of roof deformation on the translational-torsional coupling response of a single-storey building with asymmetrical height distribution of asymmetry (referred to as a single-storey eccentric building), and establishes a calculation model to derive the basic calculations. Based on the formula, a large number of calculations and comparisons are made with the computer program, and it is pointed out that under normal circumstances, the influence of the roof deformation cannot be ignored, and a simplified method for analyzing and calculating the seismic response when considering the deformation of the roof is given. This paper also analyzes and discusses the effects of seismic rotation components, estimation methods and the rationality of torsional response spectrum. The results show that both the current estimation methods and the torsional response spectra given in the relevant literature all seriously exaggerate the effect of seismic rotation components.
