    • Abstract


      Despite the considerable advantages of SPSW, there were some shortcomings concerning the system. Needing huge columns surrounding the infill plate has been the main dilemma of the SPSW system. This problem will be due to high imposed stresses to columns by the infill plate. Perforated SPSW has shown acapable method among the proposed methods to reduce applied forces to SPSW’s columns. In this paper, the optimum configuration of holes was investigated experimentally and numerically. Results indicated that the imposed forces to columns are reduced by increasing of hole area. The ultimate strength and energy absorption of perforated SPSW also are reduced by increasing of hole area. Therefore, the optimum configuration was proposed to achieve a minimum reduction in structural parameters and maximum reduction in column forces. Besides, new relations were proposed to calculate the structural parameters of the perforated SPSW. The proposed relations showed a good agreement with finite element results.
