The use of precast reinforced concrete (PC) panels to strengthen existing old masonry structures was presented in this study. Quasi-static tests were done on one unreinforced masonry wall and three reinforced wall specimens with varied connection forms to study the seismic performance of the masonry walls reinforced by PC panels and verify the effectiveness of the applied connection forms. The hysteretic response of all reinforced masonry walls differed significantly when different connection forms were applied, according to experimental results. Based on the experimental results, the proposed reinforcement method using one-sided connected PC panels can effectively improve the seismic performance of existing masonry walls in terms of shear strength, stiffness, and energy dissipation capacity. Finally, the numerical simulation models for the specimens were established to further investigate the damage mechanisms, and the hysteresis curves and failure modes of specimens obtained from numerical analysis were in good agreement with the experimental results, indicating that the proposed analytical model can be practically used to predict the performance of masonry structures strengthened by the new reinforcement technique.

PC板加筋砌体墙体抗震性​​能试验与数值研究

本研究介绍了使用预制钢筋混凝土 (PC) 面板来加强现有的旧砖石结构。对1个无筋砌体墙体和3个不同连接形式的加筋墙体试件进行准静态试验,研究PC板加筋砌体墙体的抗震性能,验证所应用连接形式的有效性。实验结果表明,采用不同的连接形式时,所有加筋砌体墙的滞后响应存在显着差异。基于实验结果,提出的采用单面连接PC板的加固方法可以有效提高现有砌体墙体的抗震性能,包括抗剪强度、刚度和消能能力。最后,
