Experimental Study on Seismic Behavior of Cold-formed Thin-walled Steel RCShear Wall

CTSRC (cold-formed thin-walled steel reinforced concrete) shear walls system studied herein is made up of cold-formed steel and concrete. Five shear walls were tested quasi-statically under low cyclic lateral loads. The characteristics including failure modes, hysteretic characteristics, ductility and stiffness degradation are investigated. Analytical result indicates that, the CTSRC shear wall structure possess adequate bearing capacity, good seismic performance and high ductility. Stirrup ratio of the restrained side columns had no significant influence on wall's bearing capacity, but walls with higher stirrup ratio show higher ductility.
