EXPERIMENTAL STUDY ON SEISMIC PERFORMANCE OF GRAVESTONES WITH INTERLOCKING REINFORCEMENT AND SEISMIC ISOLATION SYSTEM

Abstract

Gravestones are easy to overturn during an earthquake. Recently, many reinforcement measures have been developed to prevent gravestones from overturning. In this study, we focus attention on the reinforcement measures using interlocking reinforcement and seismic isolation system. 3-dimensional shaking table tests were done in order to investigate the seismic behavior of the gravestones with the reinforcement. Full-scale Japanese-type and European-type gravestones were tested, and seismic waves with seismic intensity of 6-, 6+ and 7 were used as input ground motions.
