摘要

提出一种由A,B混凝土预制侧模块、现浇混凝土层、保温层以及抗剪连接件构成的免模保温剪力墙,混凝土预制侧模块在工厂制造生产,运输到施工现场,作为现浇混凝土层的模板;通过2片免模保温剪力墙的拟静力试验,考察其施工工艺的可行性,研究A侧预制模块采用不同构造措施时墙体的整体性和协调工作性能,分析了墙体从加载到破坏全过程的破坏形态以及承载能力、滞回特性、骨架曲线、刚度退化现象、延性性能和耗能能力.根据试验结果给出了该剪力墙在工程应用中的建议.结果表明:该免模保温剪力墙施工简单可行,在A侧预制模块2种不同构造措施下,剪力墙具有良好的整体性及相近的抗震性能.%A kind of non-template insulation shear wall made of A,B side prefabricated concrete templates,cast-in-place concrete layer,insulation layer and shear connector was put forward. The prefabricated concrete template was manufactured in the factory and transported to the construction site as the cast-in-place concrete layer template.Through the pseudo-static test on 2 pieces of the non-template insulation shear walls,the feasibility of construction process was investigated.The integrity,cooperative performance of wall under the condition of different construction measures used in A side prefabricated concrete templates were studied.Meanwhile, the failure pattern, bearing capacity, hysteretic characteristics, skeleton curve, stiffness degradation,ductility and energy dissipation capacity of wall from loading to failure were also analyzed.The suggestions on the application of the shear wall in engineering were put forward. The results show that the construction of non-template insulation shear wall is simple and feasible.The shear wall has good integrity and similar seismic performance under the condition of two different construction measures used in A side prefabricated concrete templates.
