抄録

This paper presents the seismic performance of RC walls retrofitted with high strength grout
concrete. The test walls were subjected to cyclic lateral loads under lateral displacement control.
The thickness of original wall was 50mm with side columns. The test walls were designed to
replicate existing walls, of which the concrete strength was 15N/mm2~25N/mm2. The strength of
the grout concrete used for retrofitting was more than 50 N/mm2. The final collapse mechanisms
of the all test walls were shear failure mode. The maximum strength of the retrofitted walls were
more than two times of the original wall. It is anticipated that there is strong possibility of high
strength grout concrete for retrofitting the existing shear wall.
