Steel plate shear walls has high capability for earthquake energy damping as a lateral load resisting system. Since the number of steel plate shear walls with stiffeners tests are limited, therefore the comparison of force modification factor and energy absorption of them relative to steel plate shear walls without stiffener has not published up to now. For this goal two steel plate shear walls specimens with stiffeners and without stiffener was tested. Also a moment frame specimen of surround plate was tested for comparing of force modification factor and energy absorption relative to steel plate shear walls. Results show that force modification factor of steel plate shear wall with stiffeners and without stiffener is 11.5 and 12.2. Steel plate shear wall energy absorption without stiffener in various displacement is about 20 to 36 percent less than one with stiffeners. In steel plate shear walls specimens with stiffeners and no stiffener the Portion of moment frame energy absorption is about 50 and 67 percent.
