PURPOSE: An earthquake-proof reinforcement structure for an X-shaped steel concrete structure is provided to reinforce the earthquake-proof performance of structure by reducing cost and simplifying construction processes. CONSTITUTION: An earthquake-proof reinforcement structure(100) consists of: edge fixing members(1,2,3,4) attached to the inner edge of structure(20) to be reinforced; a central connecting member(5) positioned in the center of the structure; and X-shaped bracing members(6,7,8,9) having ends fixed to each edge fixing member and the other ends fixed to the central fixing member. The edge fixing members are made to steel plates and fixed to the structure by a fixing unit such as anchor bolts. The bracing members are arranged with a slope respectively with ends connected to the edge fixing members. The central connecting member of the structure is formed into a steel plate having specific thickness. The other ends of the bracing members are connected to the central connecting member concentrically. The structure having the earthquake-proof reinforcement structure has the enhanced maximum proof stress and keeps a higher intensity. In addition, the structure having the earthquake-proof reinforcement structure has the improved bending strength.
