Our civil engineers should be obliged to present a technological methods and guidance on how to design structures to resist severe earthquake attacks. It has been known that polyurea resin coating techniques is highly effective to strengthen RC structures against explosive events. Their fast reactivity and relative insensitivity to moisture make them useful coatings for large surface area projects, such as secondary containment, tunnel coatings, tank liners, and other structural components. To break a fresh method for retrofitting RC structures, this study is to find experimentally the retrofitting effects by polyurea resin coating of steel can. In drop impact tests, thin steel cans with different coating thicknesses are tested under various conditions. From test results, it is cleared that an impact resistance by polyurea coating can be remarkably improved.
