| 摘 要： | 应用钢丝网灌浆加固技术（SRG）修复村镇砌体结构具有施工简单、造价低廉以及性能优越等优点。先对一多层砌体结构开洞墙体模型进行抗震性能拟静力试验，后采用SRG技术加固受损墙体再次进行同条件试验。对比分析了加固前后墙体的破坏现象、滞回性能、刚度退化规律、耗能特性、延性与变形特征等抗震性能。试验结果表明:采用SRG技术加固受损砌体结构的破坏模式更为合理，墙体承载力、变形性能及耗能特性亦可显著提升。研究结果揭示了SRG技术加固受损砌体结构的实效性，为其在村镇建筑加固领域的应用提供技术支持。

| Abstract: | Applying the technology of steel reinforced grout(SRG) to repair the village masonry structures has many advantages, such as simple construction, low cost and superior performance. Firstly, the pseudo-static testing of the seismic performance of a muli-storey masonry opening wall mode was performed. Then, the damaged wall was retested again after reinforcing with SRG in the same condition. By comparing the tests before and after reinforcement, the damage phenomenon of the walls, the hysteretic behavior, stiffness degradation, energy dissipation, ductility and deformation were analyzed. The tests results demonstrate that the failure pattern of the latter is more reasonable. Besides, the wall bearing capability, deformation and energy consumption have been improved. The research results showed the effectiveness of SRG for reinforcing the damaged masonry wall, and provided the technological support for reinforcement of village structures. |
