Abstract: This paper considered low-cyclic reversed loading tests about five composite shear walls by pouring self-compacting concrete(SCC) into precast normal concrete(NC) wallboards, two by pouring NC. Under the conditions of constrained form of the wall marginal parts, axial load ratio and with or without insulating layer, seismic behavior of in-situ SCC and precast NC composite shear wall was studied. The whole stress process, bearing capacity, failure mode, hysteretic curve, skeleton curve, stiffness degradation curve, ductility performance, energy consumption capability and so on were analyzed, compared with precast and in-situ NC composite shear wall. The study result showed: the former had a better seismic performance and were linked very well under stress with truss bars, bearing capacity was not lower than the latter; of the two, mechanical performance, failure mode and fracture distribution were basically the same, hysteretic curve, energy consumption capability, stiffness degradation, etc, were similar; ductility factor was slightly higher than the factor of precast NC wallboards adding in-situ NC; as axial compression ratio increasing it was beneficial to improve the seismic behavior; for marginal parts using concealed column of the composite shear wall, the whole working capability was better.
