| 中文摘要: |
| 利用数值模拟方法研究低强度砂浆加固砖墙采用高延性混凝土面层加固后的力学性能。对加固试件施加低周往复位移荷载，得到高延性混凝凝土加固试件破坏特征及荷载-位移滞回曲线，并于原砖墙模型对比，验证加固方法的可行性和增强效果。研究结果显示：本研究有限元模拟的高延性混凝土单、双面加固砌体结构后的力学性能结果真实可靠，可以为历史建筑的加固和有限元模拟提供一定的参考依据。 |
| 英文摘要: |
| The numerical simulation method was used to study the mechanical properties of the brick wall reinforced with low strength mortar after being reinforced with a high ductility concrete surface layer. The failure characteristics and load-displacement hysteresis curve of the high-ductility concrete reinforcement specimen were obtained by applying a low cycle reciprocating displacement load to the reinforcement specimen, and the feasibility and enhancement effect of the reinforcement method were verified by comparing them with the original brick wall model. The results show that the mechanical properties of single- and double-sided reinforced masonry structures of high-ductility concrete simulated by finite element simulation are true and reliable, which can provide a certain reference for the reinforcement and numerical simulation of masonry structures of historical buildings. |
