저항복강 강판전단벽 골조의 구조거동에 관한 해석적 연구

초록

This study aims at investigating the performance of Low-yield point steel(HSA80 in Korea) steel plate shear walls under cyclic loading for wall thickness reduction and seismic retrofit before the experiments. The hysteretic behavior of various structural frame types, including steel plate shear wall frame (SPSWs), SPSWs with center opening, moment frame, and braced frame, was compared through finite element (FE) analysis. The target specimens consisted of three-story frames with a single span, resulting in a total of seven specimens. These specimens included four steel plate shear wall frames, one center opening frame, one moment resisting frame, and one braced frame. The analysis model for frame specimens was developed without considering detailed parts such as welded and bolted connections. The analysis results indicated that HSA80 shear steel plate wall frames demonstrated significant ductility, energy dissipation capacity, and strength compared to those of moment frame and braced frame.
