<![CDATA[Steel plate shear wall (SPSW) is one kind of steel earthquake resistant building structural stiffener that can dissipate the tremendous amount of quake energy, where the steel plate itself had been developed from years, and still in development. Ideally, SPSW is designed so all of its parts can absorb the energy of lateral force, seismic load for instance, through inelastic deformation. Because of that, the thickness of applied steel plate in a section of a building (a portal in this case) is determined by the shear force of the portal itself. In this research, experiment had been done using multiple applicable methods for the SPSW, where the use of it depends on the architect aspect and necessity. In this experiment, the specimen will be tested with some applicable lateral loading, where in the steel plate itself, there are two openings applied to the web plate. The result of the research shows some behavior changing of the dissipating energy throughout the steel plate, especially along the edge of the openings. Because of that fact, there are some performance degradation in the specimen, compared to the normal steel plate with stiffeners, which is 26.61% reduction of ultimate strength (624.01) kN at perforated specimen, compared to 850.24 kN at non-perforated specimen) and 11.5% reduction of dissipated energy]]>
