在这一部分中，为了证明第1部分中提出的方法的适用性和潜力，提出了一个用于静荷载和地震荷载作用下无筋砌体墙分析的非线性三维有限元模型。这里报告的工作也可以“独立”，因为对这一特定主题进行了详细的调查。所建立的模型将砌体视为两相材料，分别处理砖和砂浆接缝，从而考虑砖和砂浆接缝的非线性变形特征和渐进局部破坏。考虑砂浆接缝的影响，采用“界面”单元模拟沿界面的随时间滑动和分离。利用已有的解析解和实验解对本文有限元模型的结果进行了验证，表明本文模型具有较高的精度。
In this part, a non-linear 3D finite element model for the analysis of unreinforced masonry walls subjected to static and seismic loads is presented, in order to demonstrate the applicability and potential of the method proposed in Part 1. The work reported here could also stand “on-its-own”, due to the detailed investigation made on this particular subject. The model developed considers masonry as a two-phase material, treating bricks and mortar joints separately, thus allowing for nonlinear deformation characteristics and progressive local failure of both bricks and mortar joints. The influence of the mortar joints is taken into account by using ‘interface’ elements to simulate the timedependent sliding and separation along the interfaces. Analytical and experimental solutions available in the literature have been employed to verify the results obtained from the present finite element model, showing that it is capable of a high degree of accuracy.
