Description

  The present invention relates to a reinforcing structure for a structure, a reinforcing method, a reinforcing block, and a seismic wall.

As a reinforcement method for new structures or existing structures, a reinforcement member called a brace made of steel frame or steel pipe is diagonally installed in the frame opening surrounded by columns and beams along the diagonal direction. Is well known (see Patent Document 1, etc.). The brace plays a role of resisting external force due to an earthquake or the like input to the frame opening and suppressing deformation of the frame opening.
