Shear capacity prediction of steel plate shear walls with precompression from columns

Abstract

SummaryThis paper investigates the shear capacity of the unstiffened steel plate shear walls with gravity loads from the adjacent boundary columns that is produced during the construction process. The distribution and transferring of gravity loads between boundary columns and the infill steel plate are proposed. Then, the infill steel plate is partitioned into 3 zones bounded on the effective length, the inclination angle, and shear capacity of each zone that is proposed and discussed, and the shear capacity of the infill steel plate is summed over the 3 zones. Finally, based on the three specimens tested by Park et al. (2007), shear capacity prediction of 18 more numerical steel plate shear wall specimens with the axial stresses of the boundary columns equal to 50 MPa, 100 MPa, 150 MPa, 200 MPa, 250 MPa, and 300 MPa are analyzed.
