In Japan, how to design structures to resist severe earthquake attacks is still one of the challenges today for our civil engineers. Then we should be obliged to present technological methods and guidance for prevention. A polyurea resin coating techniques has been well known that it is of effective to strengthen RC structures against impact and explosive events. To break a fresh method for retrofitting masonry structures against severe earthquakes, this study is to find experimentally the collapse preventive effects by polyurea resin coating of masonry structures. In shaking table tests, masonry block and brick walls with or without coating are tested. From test results, it is found that collapse prevention by polyurea coating can be remarkably improved.
