摘　　要：石墙是石结构抵抗地震作用的重要抗侧构件,其抗剪性能对石墙单元及石结构整体地震反应至关重要.本文首先对条石砌筑石墙灰缝抗剪性能的研究现状进行了分析,主要内容包括:已有试验研究的加载装置、研究参数和抗剪承载力计算方法,以及有限元数值模拟分析方法.在此基础上,提出了石墙灰缝单向抗剪的剪切滑移本构模型,并采用ABAQUS有限元分析软件对石墙灰缝双剪试验进行了数值模拟,其结果与试验结果吻合较好.The shear behavior of stone-mortar ioints is an important parameters to estimate the seismic behavior of stone masonry buildings. This paper provides the process of shear behavior study on dry-laid stone masonry wall with inserted mortar joints, including experimental study as well as theoretical and simulated analysis of mortar joints shear behavior. The comparison of different test setups and the determination of joint shear strength are presented. In addition, based on the analysis, a simplified constitutive model for the shear slip deformation of stone masonry joints is proposed, which can be used for numerical analysis. The simulated results predicted by this study shows the same trend to the available experimental results.
