Since masonry structures are prone to collapse in earthquakes, a novel joint reinforcement method with a polypropylene band (PP-band) and cement mortar (CM) has been put forward. Compared with the common reinforcement methods, this method not only facilitates construction but also ensures lower reinforcement cost. To systematically explore the influence of joint reinforcement on the seismic performance of masonry walls, quasi-static tests were carried out on six specimens with different reinforcement forms. The test results show that the joint action of PP-band and CM can significantly improve the specimen’s brittle failure characteristics and enhance the integrity of the specimen after cracking. Compared with the specimen without reinforcement, each of the seismic performance indexes of the joint reinforced specimen had obvious improvement. The maximum increased rate about peak load and ductility of the joint reinforced specimen is 100.6% and 233.4%, respectively.

由于砌体结构在地震中容易倒塌，因此提出了一种新型的聚丙烯带（PP-band）和水泥砂浆（CM）联合加固方法。与常用的加固方法相比，该方法不仅施工方便，而且加固成本较低。为系统探讨节点配筋对砌体墙体抗震性​​能的影响，对6个不同配筋形式的试件进行准静力试验。试验结果表明，PP-band和CM的共同作用可以显着改善试件的脆性破坏特性，增强试件开裂后的完整性。与未加筋试件相比，加筋试件各项抗震性能指标均有明显提高。
