Outline of Research at the Start

URM infills are vulnerable to OOP collapse. However, the realistic performance of infill is still unclear and there is still a lack of sustainable strengthening methods. Hence, this research investigates the realistic seismic performance of infills, and proposes sustainable strengthening methods.
