THE EVALUATION METHODS OF THE PERFORMANCE OF REPAIRED REINFORCED CONCRETE MEMBERS, AND THE SEISMIC PERFORMANCE OF REPAIRED CONCRETE STRUCTURES

Abstract

 Recently, it was being revealed that the performance of repaired reinforced concrete (RC) members and re-repaired RC members was different from the performance of RC members. In previous studies, we revealed the performance (re-)repaired RC members was affected by damage degree of longitudinal reinforcements, repairing materials and repairing methods. In this paper, we tried to quantify the performance of (re-)repaired RC members. Firstly, we proposed the seven models of stiffness and maximum capacity point of (re-)repaired RC members, and proposed the tri-linear skeleton model of them. Secondly, by using these models, we evaluated the seismic performance of repaired rigid-frame viaducts.
