通过对混凝土结构补强加固措施存在的问题进行分析,给出了混凝土-复合层新型结构具体形式,提出了混凝土-复合层新型结构施工具体流程;对混凝土、尼龙带混凝土和胶黏带混凝土强度进行了试验测定。结果表明:尼龙带和胶黏带混凝土压缩韧性增强,对于混凝土结构补强和抗震性能作用提高较好。高性能数值计算结果表明:拉伸破坏是立柱的主要破坏模式,剪切破坏是次主要破坏模式;混凝土+加固带+多孔金属复合层结构型式为混凝土-复合层结构优选型式,与混凝土-复合层结构补强特性试验测试研究结果一致。
By analyzing the problems existing in the reinforcement and reinforcement measures for concrete structures, concrete forms of the concrete-composite layer structure are given, concrete concrete-composite layer structure construction processes are proposed, and the concrete, concrete with nylon tape, and adhesive tape concrete strength are proposed. Test measurements were made. The results show that the compression toughness of the nylon belt and the adhesive tape reinforced concrete is better for the reinforcing and anti-seismic performance of the concrete structure. The high-performance numerical calculation results show that tensile failure is the main failure mode of the column, shear failure is the main failure mode, and the structure of concrete+reinforcement zone+porous metal composite layer is the optimal type of concrete-composite layer structure, and is combined with concrete-composite Layer structure reinforcement test test results are consistent.
