| Abstract: | The RC frame strengthened with steel plate in the case of reforcing excited by e arthquake are studied with non-linear finite element analytical method. Finite element method models are developed to simulate the behavior of RC structures st rengthened with externally bonded steel plate sheets in case of reforcing. The t ime-history analytical method of earthquake response for reinforced concrete fr ame structures strengthened with steel plate is presented. Finally, a 10-floor R C frame strengthened with steel plate excited by El-centro earthquake are analy zed. |
