配筋砌块砌体短肢剪力墙结构性能试验研究

Research on the Structute Behavior of the Reinforced Block Short-leg Masonry Shear Wall

通过对2片T形截面配筋砌块砌体短肢剪力墙足尺试件低周反复荷载试验,研究分析了这种新型墙体的破坏特征、承载能力、滞回性能和变形能力等方面的性能,并着重分析了水平筋和宽翼缘的影响.试验结果表明,配筋砌块砌体短肢剪力墙具有良好的结构性能,发生了弯剪型破坏,翼缘的存在和水平筋的设置有效改善了墙体的延性性能.

The hysteretic characteristics and deformation, the bearing capacity and failure mode of the new wall structure are researched by the horizontal cyclic loading experiments of two T-section specimens, and put emphasis on the influence of horizontal steel and wide flange. The results of experiment show ： the seismic behavior of the reinforced block short-leg masonry sheaf wall structure is very good, and it＇s failure of bending and shear, wide flange and the placement of horizontal reinforcing steel bar can improve ductility of the wall.
