Abstract

In this paper, the behavior of steel plate shear walls (SPSWs) with stiffened rectangular openings used as windows or doors in buildings is studied using the finite element method, and compared with corresponding systems without openings. In the case of such large openings, the use of LOCAL BOUNDARY ELEMENTs (LBE) around the opening to anchor and transmit the in fill plate tension forces to the surrounding boundary members (beams and columns) at their ends is inevitable. It is found to be more economical to extend the opening to the story height, whether needed or not, so that horizontal LOCAL BOUNDARY ELEMENTs will not be needed, and which would lead to considerable cost saving in construction. Therefore, the openings are assumed to have a constant height and extend along the full height of the systems. A number of single-story SPSWs, with different aspect ratios, having four different opening location patterns and various opening lengths, are considered for this research. According to the design code recommendations, SPSWs are designed per the capacity design principle. The adequacy of the finite element modeling approach for representing the pushover and cyclic responses of SPSWs is verified through comparisons with experimental results. Results show that due to the introduction of openings and LBE, plate strength decreases proportionally with the decrease in plate area, while the frame strength always increases. As a result, the overall system strength may increase or decrease, depending on the location and length of the opening. The STIFFNESS and DUCTILITY of SPSWs with stiffened openings are always less than those of the corresponding SPSWs without openings, and, generally, the ratios of the STIFFNESS and DUCTILITY values of SPSWs with openings to those of corresponding SPSWs without openings decrease linearly with the relative length of the openings. The system aspect ratio has no significant effect on the ratios of the strength, STIFFNESS and DUCTILITY of SPSWs with openings compared to those of the corresponding SPSWs without openings. Moreover, provided that the opening length is not very long, the introduction of openings and LBE increases the energy dissipation capacity of the system.
