SHAKING TABLE MODEL TEST FOR DEVELOPMENT OF ASEISMIC COUNTERMEASURE OF MASONRY WALL IN NARROW SITE

Abstract

In this study, a series of shaking table model tests was carried out to investigate into the resistant mechanism of the proposed reinorcement methodology, which combines inclined soil reinorcement with failure prevention net. It is found from the model tests that the failure prevention net could work to restrict dropping of the wall facing block, and to propagate the pull out resistance mobilized by the soil reinorcement. In additions to the above, especially when the wall displacement become relatively large, mobilization of the resistance thanks to the flexural rigidity of the soil reinorcement was also indicated as well as the pullout resistance. As a result of the above reinorcement mechanism, proposed method could effectively improve seismic perormance of the masonry wall.
