| 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对比分析,探讨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.

| Abstract: | By means of experiment on prestressed diagonal bar-reinforced brick masonry walls and plain brick masonry walls as well subjected to low horizontal cyclic lateral loading,some technical indexes such as appearance and development of crack in walls,shear strength of walls,and hysteresis behavior of the brick masonry walls were compared and analyzed.The influence of prestressed diagonal bar-reinforced masonry structure on earthquake resistance performance was discussed,also.Test results showed that the shear s... |
