在试验数据的基础上，采用多面界面模型，分别假定石材单元和接缝为弹性和非弹性，模拟了干式无沥青锯切石材砌体单调和反向循环荷载-位移滞回曲线。采用有限元软件Diana version8.1进行数值模拟。岩石单元采用8节点连续平面应力单元进行高斯积分，节理单元采用6节点零厚度线界面单元进行Lobatto积分。本文概述了试验研究工作的概况和所进行的数值模拟的细节，并报告了数值单调荷载-位移曲线和反向循环荷载-位移滞回曲线。
A numerical simulation based on experimental test data has been carried out to model the monotonic and reversed cyclic load-displacement hysteresis curves of dry-stack mor- tarless sawn stone masonry using a multi-surface interface model where stone units and joints are assumed elastic and inelastic respectively. Finite element software, Diana version 8.1 has been employed to carry out the present numerical modelling. The stone units were modelled us- ing an eight node continuum plane stress elements with Gauss integration and the joints were modelled using a six node zero thickness line interface elements with Lobatto integration. This paper describes outline of the experimental research work and details of numerical modelling carried out and reports the numerical monotonic load-displacement curve and reversed cyclic load-displacement hysteresis curves.
