چکیده مقاله
In this study, the seismic reliability of a short rise reinforced concrete RC building retrofitted using knee steel braces is investigated through non linear dynamic analysis As a case study, a three storyRC building was selected The design of selected sample building was made with reference to Iran seismic resistant design of building code of practice 2800 The effectiveness of using knee braces in retrofitting buildings was examined The effect of distributing the steel braces over the height of theRC frame on the seismic performance of retrofitted building was studied For the strengthening of the original structure knee bracing frame KBF was applied with four different spatial distribution in the structure The improvement of seismic reliability achieved through the use of knee braces wasevaluated by comparing the displacement of stories As a result of this study, the improvement in seismic performance of this type of short rise RC building resulting from retrofits by steel knee braces was obtained by stories displacement diagrams
