Paper Title
In-Plane Quasi Static Cyclic Testing of Reinforced Concrete Frames Retrofitted with Eccentric Steel Braces
Abstract
Steel bracing is an effective and economical retrofitting technique for upgrading deficient reinforced concrete moment resisting frames typically found in the developing countries. Steel bracing not only increases the strength, stiffness and energy dissipation capacity of the system but also provide sufficient ductility under an earthquake event. This paper numerically investigates the seismic performance of eccentric steel braces connected diagonally to reinforced concrete beam at a distance of Lbeam/6 from the face of the column. Static time history analysis was performed on a single story reinforced concrete bare frame and eccentric steel brace retrofitted frame using a finite element program. Results showed that frame retrofitted with eccentric steel brace changes the lateral load transfer path and reduces the demands on the most crucial zone beam-column joint and as a result increases the strength, stiffness and energy dissipation capacity of the frame as opposed to bare frame.
