ABSTRACT

As a promising lateral load resisting elements in new or retrofit construction of buildings, buckling-restrained steel plate shear wall (BRSW) clamed with concrete plates had gained a great deal of attention of researchers and engineers. However, almost all of BRSWs being studied and employed are in small height-to-width ratio. Actually, in some situations, slim BRSW may be more serviceable if there do not have enough space to put wide BRSWs. Moreover, a new type BRSW was proposed in this paper. Several experimental investigations had been conducted on this BRSW, including monotonic loading tests and cyclic loading tests on four sets of specimens with different height-to-width ratio from 2:1 to 4:1, as well as comparative tests on normal steel plate shear walls. The detailing of the walls was modified to improve their energy dissipation. A simplified equivalent cross-brace model was presented and verified by finite element analyses.
