Abstract This research aims at the seismic assessment and understanding of a traditional loadbearing system incorporating horizontal timber elements into earth brick masonry walls. In order to characterize the global behavior of the loadbearing device, an experimental campaign was performed on the constituents (i.e. bricks and mortar) and on masonry samples. Compression tests were carried out on four geometries of earth brick samples and three geometries of earth mortar samples. As the methods to obtain the compressive strength of earth material are still discussed within the scientific community, a focus was made on different configurations tested. Uniaxial compression tests were performed on two earth brick wallets. Then, two brick walls (with and without horizontal timber reinforcement) were submitted to lateral quasi-static cyclic load. A LVDTs system and a stereo correlation image system were coupled to study the experimental response of the reinforced and unreinforced walls. This investigation led to estimate the lateral strength, the stiffness degradation and the dissipated energy of both reinforced and unreinforced masonry walls. Moreover, it allowed the comparison between the failure modes of the two types of wall. This analysis brings light on the mechanical impact of the horizontal reinforcement.

木材夹杂物对土石墙抗震性能影响的试验分析

摘要 本研究旨在对将水平木材元素纳入土砖砌体墙的传统承重系统进行抗震评估和理解。为了表征承重装置的整体行为，对成分（即砖和砂浆）和砖石样品进行了实验活动。对四种几何形状的土砖样品和三种几何形状的土砂浆样品进行了压缩试验。由于科学界仍在讨论获取地球材料抗压强度的方法，因此重点关注测试的不同配置。在两个土砖钱包上进行了单轴压缩测试。然后，两个砖墙（有和没有水平木加固）承受横向准静态循环荷载。LVDTs 系统和立体相关图像系统耦合以研究加固和未加固墙的实验响应。这项调查导致估计了加固和未加固砌体墙的横向强度、刚度退化和耗散能量。此外，它允许比较两种类型的墙的破坏模式。该分析揭示了水平钢筋的机械影响。
