Effects of loading rate on mechanical behavior of SRC shearwalls

In order to investigate the effect of the loading rate on the mechanical behavior of SRCrnshearwalls, we conducted the lateral loading tests on the 1/3 scale model shearwalls whose edge columnsrnwere reinforced by H-shaped steel. The specimens were subjected to the reversed cyclic lateral load under arnvariable axial load. The two types of loading rate, 0.01 cm/sec for the static loading and 1 cm/sec for therndynamic loading were adopted. The failure mode in all specimens was the sliding shear of the in-filled wallrnpanel. The edge columns did not fail in shear. The initial lateral stiffness and lateral load carrying capacityrnof the shearwalls subjected to the dynamic loading were about 10% larger than those subjected to the staticrnloading. The effects of the arrangement of the H-shaped steel on the lateral load carrying capacity and thernlateral load-displacement hysteresis response were not significant.
