| Research Abstract |
This paper shows the retrofitting technique of beam-column joints of reinforced concrete structures. The technique proposed here is used for existing structures with weak joints. Joints in some buildings failed in Hyogoken-Nanbu earthquake disaster. However, no effective technique had been proposed to retrofit the joints. The author proposed two methods of the retrofit. The one method uses PC bar prestressing, and the other uses steel haunches and steel plates. Both methods are proved to be effective by experiments.
