Scope

This specification is formulated in order to make the reinforcement of masonry structures reliable in technology, safe and applicable, economical and reasonable, and ensure quality. This code is applicable to the reinforcement design of masonry structures of houses and general structures. Before the masonry structure is strengthened, reliability appraisal should be carried out according to the relevant provisions of the current national standards "Industrial Building Reliability Appraisal Standard" GB 50144 and "Civil Building Reliability Appraisal Standard" GB 50292 according to different building types. When it is carried out in combination with seismic reinforcement, the seismic capacity appraisal should be carried out according to the relevant provisions of the current national standard "Building Seismic Appraisal Standard" GB 50023. The reinforcement design of the masonry structure shall not only comply with the provisions of this code, but also comply with the provisions of the current relevant national standards.
