Abstract

This research presents the seismic strengthening of a reinforced concrete structure which had not been designed for seismic resistance. The studying was focusing on analysis of an existing structure and selecting of a strengthening method which consider influencing factors with construction. An existing moment resisting frame system had been selected and analyzed by equivalent static method according to design specification for seismic resistance (DPT. 1302-52). Results of the analysis showed that over 60 percent of all columns were not satisfied and have to be strengthened. Steel Braced Frame has been selected for strengthening. As a result, the retrofitted structure can be safely used in comply with seismic specification.
