Earthquake-proof reinforcement works for structures have been advanced since Hyogoken-Nanbu-Earthquake. However, reinforcement work for masonry walls have not been carried out yet, because the actual conditions of the masonry wall and the deformation mechanism of the masonry wall during the earthquake has not been clarified. Therefore, we investigated the actual conditions of the masonry wall along the railway line, and performed some experiments of scale model masonry walls using a shaking table. The deformation process of the masonry wall during the earthquake was clarified by these model experiments. This paper deals with: (1) outline of new earthquake-proof reinforcement methods for masonry walls, (2) model tests using shaking table to confirm the effects of these methods, and (3) the study results of the execution methods to be applied to actual reinforcement work.
