Rehabilitation of Reinforced Concrete Structures--The Integration of Experimental Results and Analytical Models

Research on rehabilitation of non-ductile reinforced concrete structures located in zones of high seismic risk has been underway at The University of Texas at Austin since 1981. A sampling of details and results from selected experimental programs investigating repair and strengthening of reinforced concrete non-ductile frame buildings is presented. Researchers at The University of Texas have integrated knowledge about the behavior of non-ductile elements and systems, retrofitted members, subassemblages, and superassemblages into non-linear time-history analysis models. These models have been used to investigate the response of buildings, retrofitted with techniques studied in the laboratory, to a variety of strong-motion earthquake records.
