Abstract
How to design structures to resist severe earthquake attacks is one of the challenges today for our civil engineers, and then we should be obliged to present a technological methods and guidance. A polyurea resin coating techniques has been known that it has effectiveness to strengthen RC structures against impact and explosive events. To break a fresh method for retrofitting RC structures, this study is to find experimentally the retrofitting effects by polyurea resin coating of plate/wall members. In horizontal impact tests, various plate/wall members with different coating thicknesses are tested. From test results, it is found that an impact resistance by polyurea coating can be remarkably improved.
