【摘要】 通过预应力斜拉筋加固的砖墙与无筋砖墙在低周反复水平荷载作用下的试验,对墙片开裂、裂缝发展过程、抗剪强度、滞回特性等技术指标进行了对比分析,探讨了预应力斜拉筋加固对砌体结构抗震性能的影响。试验结果表明,砌体结构的抗剪强度、结构开裂荷载、结构延性随着预应力的增加而增大,墙体裂缝随着预应力的增加细而密。预应力斜拉筋技术为砌体结构提出了一种新加固方法。更多还原

【Abstract】 By comparing the test of prestressed diagonal bar reinforcement brick masonry and plain brick masonry wall,under cyclic lateral loading,the appearance and development of crack,shear strength,hysteretic behavior of the brick masonry walls are studied.To discussion the prestressed diagonal bar reinforcement to masonry structure influence of earthquake resistance performance.Test results showed that the shear strength of masonry structures,structural cracking load,structural ductility will increases with the increase of prestressed.Cracks form of distribution become fine and tight with the increase of prestressed.Technology of prestressed diagonal bar reinforced masonry structure,a new method of reinforcement.更多还原
