The objective of the present work is to study the response of dry stone walls subjected to out-of-plane forces and the influence of block‘s rugosity, joint arrangement, and border conditions. For this purpose, a series of scaled-down experimental tests on a tilting table and 3D numerical modeling using discrete elements, DEM, are proposed. In the numerical model, the applicability of some types of discrete elements is first studied. The preliminary analysis gives us useful information about the effects of the joint disposition and the border conditions in the response. Finally, the sensitivity of the response of the blocks to the parameter’s variations is analyzed. The experimental and numerical results show that the DEM method is adequate to simulate the failure mode, the displacement, and the lateral load of stone walls due to out-of-plane lateral loads considering the effect of the irregularity of the blocks, joint arrangement, and border conditions.

目前工作的目的是研究干石墙在平面外力作用下的响应，以及块体粗糙度、节点布置和边界条件的影响。为此，建议在倾斜台上进行一系列按比例缩小的实验测试和使用离散元素 DEM 的 3D 数值建模。在数值模型中，首先研究了某些类型离散元的适用性。初步分析为我们提供了有关联合部署的影响和响应中的边界条件的有用信息。最后，分析了块的响应对参数变化的敏感性。实验和数值结果表明，DEM 方法足以模拟破坏模式、位移、
