| Abstract | ||
| 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. | ||
