摘要
本文运用随机振动振型分解均值反应谱方法，对砖结构层间地震剪力、弹性反应变形进行了分析，并对其阻尼模型进行了研究；阐述了基于单体建筑实测数据对层间墙体抗剪承载力进行统计分析的方法；确立了多层串联结构体系“小震不坏”的抗震可靠度评价模型。通过承载能力和小变形能力的抗震可靠度分析和比较，指出了砖结构按承载能力进行抗震可靠度分析和设计计算的实质。
By the method of mode-type resolving and average spectrum in ran-dom vibration,storey-shear-force and elastic storey-drift response of brick buildings are discussed under“small earthquakes”,its damping model is also studied.A statistical method for shear-resisting capacity of storey-wall is suggested according to the test results. Amodel is established to evaluate the aseismic reliabilitv of multi-storey strung structures under“small earthquakes”.The aseismic reliability of brick buildings is analyzed and compared based on criterions of bearing and deforming capacities,which demonstrates the essence of aseismic reliability analyses on the basis of bearing capacity,
