In this paper effects of the placement of various stiffeners and opening on the interaction behavior of steel plate shear walls and precast concrete frame, has been investigated. Steel plate shear walls has been bolted to concrete frame, by use of embedded plate in boundary concrete elements. Push over and dynamic analysis under seven earthquake acceleration in ABAQUS software, was done.
The results showed that the proposed connection, by keeping up its stability and strength, showed appropriate function in the route of load bearing of shear wall. Also it was observed that adding steel plate shear wall to concrete frame increased initial stiffness, base shear and dissipated energy 4, 4.3 and 340 times, respectively. The sample with opening in diagonal line and horizontal and vertical stiffeners, had maximum dissipated energy (22% increased). This sample showed the maximum relative displacement (increased 2 times) and minimum base shear force (decreased by 10%). Adding horizontal and vertical stiffeners to simple sample, increased dissipated energy by 16% while, the sample with diagonal stiffeners decreased dissipated energy by 25%. This model showed the minimum relative displacement (decreased by 15%) and maximum base shear force (increased by 7%). Placing the opening at the middle of sides in this model, increased dissipated energy by 35%.
