This research is earthquake-proof reinforcement design for old school buildings. At present, the old school buildings in our country mostly reflect no earthquake-proof design, so occurrence of earthquakes may result in a lot of human damage. Recently, the earthquake-proof reinforcement of school buildings are formally realized during the remodeling process of old schools. Most reinforcement methods perform reinforcement with a bearing wall or earthquake-proof damper. These reinforcement methods mainly use anchor bolts as a method of combining the reinforcing members and the existing structure, and use a wet method simultaneously. These methods tend to reduce the bearing capacity of the existing structures and take a long time in construction. This research sought to construct steel reinforcements in a dry method in order to complement these disadvantages. This research analyzed the behavior of rebar reinforcements as a compressing member using elastic links in order to prove this dynamically. The analysis result proved that the reinforcing members endure the earthquake load enough while acting as a compressing member during occurrence of earthquakes. Therefore, it is hoped that the reinforcement method presented by this research might be a little help to the earthquake-proof reinforcement of the old school buildings. The reinforcing method presented by this research is one proved by conceptual and dynamic analysis only, so it is thought that research and verification will be necessary through the construction detail and actual mock-up test of the existing structures and reinforcing members in the future.
