ABSTRACT
ABSTRACT: Through the adding floors reconstruction of an office building, this paper explores the feasibility of adding floors, and elaborates reinforcement construction points. In order to reduce the load increment, part of the wall mortar on the one storey is replaced by higher strength mortar. Meanwhile the original building needs to add ring beams and columns. According to scientific and rational seismic strengthening, results show that the integrity and service life of multistory masonry structure increases effectively. Through design analysis of above mentioned process, some effective methods are introduced, which can be used as reference for the reinforcement and reconstruction of similar projects.
