摘要
通过1:2预应力与非预应力带圈梁、构造柱砖墙在低周反复水平荷载作用下的对比试验,研究了墙片的裂缝出现与开展过程、破坏机理、滞回特性、强度、刚度、延性及耗能能力。本文仅就其抗裂及承载力进行了论述,说明在砖墙中施加预应力能明显提高其抗震性能,并提出了有关抗裂及极限承载力的计算方法,计算结果与试验相当吻合。
By comparing the tests of prestressed and nonprestressed brick masonry walls with peripheral beams and Constructional columns, under cyclic lateral loading,the apperaence and development of Cracks,failure mechanism,hysteretic behavior,strength,stiffness,ductility and ener-gy dissipation of the brick rnasonry walls arc studied.Only the crack resistance and bearing capacity of walls are discussed in this paper.It is shown that prestressing on brick masonry wall can obviotisly improve its seismic behavior.Morcover,calculating methods for the crack resistance and the ultimate bearing capacity are presented,and the caculating results are identical with the tests.
