Abstract: This paper presents an experimental investigation on the flexural behavior of cross-connected brick masonry infill wall panels supported on reinforced concrete beam grids above and below the walls. The experimental program was comprised of six wall systems. The effect of change in lower beam stiffness relative to the wall and the geometry of the main walls were investigated. From the results of the experimental tests, the increase in the depth of the lower beam grid reduces the deflection, resulting in an increase in the load carrying capacity of the wall. Further, the stiffness of the main walls affects the deflection and the failure load of the cross walls.

Key words: brick masonry infill walls, reinforced concrete beam grid, main and cross walls, stiffness, deflection, crack pattern, failure load

摘要： 对墙上、墙下由钢筋混凝土梁格支撑的交叉连接砖砌体填充墙板的受弯性能进行了试验研究。实验方案由6个墙面系统组成。研究了下梁相对于墙的刚度变化和主墙的几何形状的影响。从测试结果来看，下梁格栅深度的增加减小了挠度，导致墙体承载能力的增加；主墙的刚度对横墙的挠度和破坏荷载也有影响。
