摘　　要：应用斜拉筋加固技术,在低周反复荷载作用下对加固砖砌体的抗震性能进行了试验研究,对结构的滞回特性、破坏形态以及结构的抗剪能力、变形、耗能等技术指标进行了对比分析,探讨了斜拉筋对砌体结构抗震性能的影响。试验结果表明,随着斜拉筋加固的配筋量的增大,砌体结构的抗剪能力增强,结构延性增大。斜拉筋加固为砌体结构的加固提供了一种新技术。In the application of the strengthening technology of diagonal draw steel bar, aseismatic behavior of strengthened block walls was experimented under lower cycle reversal loads. Such characteristics as the individual walls＇s hysteresis loop destruction,level load bearing capacity deformation and energy consumption are qualitatively analyzed.The influence of aseismatic behavior was also studied, The test result indicate as the increase of the quantity of reinforcement, the level load bearing capacity of masonry structure enhancement and the ductility improve. The strengthening technology of diagonal draw steel bar proposed a new technology of block walls.
