Abstract:: 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.
