| Research Abstract |
In order to make an economical seismic response controlling system by securing a ductile failure mode of structural walls, a hybrid system using corrugated steel shear panel proposed by Mo and Perng in 2000 was revised to make it effective in dissipating seismic energy in practice. In this study, the hybrid system with corrugated shear panel was revised to prove that the shear capacity and the shear stiffness of corrugated steel shear panels were fully utilized with sufficient anchorage at the interface between surrounding RC members and shear panels. In an experimental phase, a stud-type anchorage often used in bridge box girders was employed in four half-scale specimens and static cyclic loading was applied. The behavior was stable if the number of studs satisfied the Japanese design guidelines. The behavior after buckling of the corrugated panel was ductile and degradation in lateral load carrying capacity was about 20% even at 5% drift angle. However, even specimens with half number of studs showed the similar behavior. All hybrid frames showed more than 30% increase in lateral load carrying capacity from the original RC frame. In an analytical phase, a nonlinear frame analysis was conducted to evaluate the effect of corrugated steel shear panel on the performance of the reinforced concrete frame. The analysis simulated the behavior of frames with different fixity of the shear panels well. Design method to optimize the amount of anchorage due to shear capacity of frames and corrugated steel shear panels is established with this analysis model.
