Abstract: An innovated steel-concrete composite structural wall, CTSRC (Cold-formed Thin-walled Steel Reinforced Concrete) shear wall, is presented. Five CTSRC shear walls and one steel bars reinforced concrete (RC) shear wall are tested quasi-statically under low cyclic lateral loads for shear performance, and the effects of longitudinal reinforcement in the edge member，the anchorage of the cold-formed thin-walled steel, and the steel meshes are investigated. The test results show that CTSRC shear walls have adequate ductility and deformability in view of their failure process from integral wall to slit wall, which is different to that of RC walls. The study proves that the steel meshes increase the wall’s bearing capacity, but impair its ductility and deformability. It can be found that anchoring steel profiles into the basement makes the later bearing capacity stable, and that the wall’s behavior is improved with the increase of longitudinal reinforcement in the edge member. Based on above observations, the reasonable configurations of the details of CTSRC shear walls are suggested for actual applications.
