Seismic Performance of Existing RC Structural Walls Retrofitted in Flexure by Wall End Plate

A study was conducted for the flexural retrofit of an old apartment house composed a reinforced concrete (RC) shear wall structure. For wall, vertical performed to both ends targeting slender improve performance. The materials were steel plate, epoxy, and non-shrink grout, they connected existing using post-installed chemical anchors. at broken retrofitted as much necessary maintain wall’s length. points be noted are fracture welded part anchor’s pulling. After real scale specimen fabricated by simulating effect experimentally verified breaking ends, retrofitting applying repeated cyclic lateral loads. total three specimens plates tubes. Since this experiment evaluated performance, with cantilever setting. analyzed through load–displacement relationship, stiffness degradation, energy dissipation, this, bond behavior verified.
