To study the failure mechanism and seismic performance of prefabricated steel reinforced concrete composite walls with steel castings, quasi-static tests were carried out on steel reinforced concrete composite walls with a scale of 1∶2. The steel reinforced concrete composite walls under low cycle reciprocating loads were contrastively analyzed on failure processes, failure modes, hysteretic characteristics, shear capacity, deformation capacity, wall damage and energy dissipation capacity by changing their built-in steel types. The experimental results showed that the steel castings used for welded structures have high strength, stiffness and safety, and can be applied to the on-site prefabricated connections of steel reinforced concrete composite walls. The overall shear failure occurred in steel reinforced concrete composite walls, and their shear capacity, energy dissipation and deformation capacities were greatly improved compared with those of reinforced concrete composite walls. In combination with engineering practice, an on-site assembly scheme for steel reinforced concrete composite walls was given.
