摘　　要：通过对不同类型的预应力混凝土小型空心砌块砌体墙进行水平低周反复荷载试验,研究了预应力砌体的破坏形态、滞回特征、延性等抗震性能。试验结果表明:在墙顶施加预应力可以提高墙体的抗剪强度和变形能力,改善墙体的抗震性能。Based on the low-frequncy cyclic horizontal loading tests on different types of prestressed small-size concrete hollow block masonry walls, the cracking shape, wall failure pattern, hysteretic characteristics, ductility and seismic behavior of prestressed masonry have been studied. The experimental results show that the bearing capacity of shear and deformation property of the masonry walls is increased and the seismic behavior of the prestressed walls is improved.
