In this study, the seismic behavior of reinforced concrete(R/C) frame strengthened with steel brace is analytically and experimentally investigated. R/C frame strengthening by installation of prestressed brace frame and comparison is made of non prestressed brace frame. The test and analysis results demonstrate that the seismic performance of R/C frame effectively enhanced by prestressed steel brace than non prestressed steel brace.

This study presents seismic behavior of R/C frame retrofitted prestressed steel brace. To evaluate seismic performance of R/C frame retrofitted prestressed steel brace, the test performed analysis and experiment. The results demonstrate that the seismic performance R/C frame effectively enhanced by prestressed steel brace than non ductile R/C frame.

Many reinforced concrete moment resisting frame buildings in seismic zones lack strength and ductility. A Brace system may provide an economic advantage for the retrofit of these structures. Brace generally increase the strength and rigidity of frames under the influence of lateral loads such as earthquake. The main object of this research is to propose finite element analysis technique of the brace which considers the interaction of frame and brace.
