Proposed in this study is a retrofitting technology that can be applied on exiting masonry buildings. It employs pre-cast reinforced concrete panels to confine existing masonry structure. The pre-cast members constitute a frame which encomprises the existing building. The confinement effectively improves the ductility, strength, and stiffenss of masonry structures. Moreover, the reinforced concrete panels are fabricated in factory, significantly reduces the situ construction and construction period. To demonstrate the design theory, construction organization, and seismic performance of the retrofitted structure, a full-scale structure was tested physically. Pseudo-dynamic testing results indicate the feasibilty and effectiveness of the proposed retrofitting technology.
