Case Analysis of Seismic Reinforcement of Historical Buildings----Based on Reinforced Concrete Frame Structure

China has a long history and has survived many excellent historical buildings, These historic buildings have inadequate capacity or do not meet the requirements of earthquake resistance and need to be reinforced. This paper briefly describes the seismic reinforcement method of concrete reinforced concrete structures at first, and then made a contrastive analysis on the historical buildings before and after the reinforcement. Finally, made a comment on the contradiction between the method of aseismatic reinforcement and the protection principle of historic buildings.
