The seismic design criteria are determined to install the reinforcement structure through the reinforcement design of existing facilities. Most braces are designed to be tensile, so the three equipments are large, and when subjected to compressive forces, there is a problem that the elastic buckling does not act as a brace. In addition, since most of the infrastructure and plants, such as steel structures to be reinforced during operation, there was a problem that welding work is not possible.

Since the plate is not reinforced, there was a problem that buckling occurs in the bracing plate during compression.

The non-buckling brace for seismic reinforcement of steel structures of the present invention can be fastened by bolting without using a bonding method such as welding by constructing a reinforcement to surround the core formed of H-shaped steel, and is very easy even during operation of steel structures such as electric power facilities. It can be constructed in a simple manner, reinforcing the weak axis of the core web and expanding the cross section of the core to improve the cross-sectional performance, so that the buckling does not occur even during compression, leading to stable hysteretic behavior even under repeated loads such as earthquakes. There is a very useful effect that can be increased.

The brace under tension can be compressed by the compressive force during an earthquake, and because the structures such as plants are pin-bonded, the only transverse resistance element is brace. In this case, steel structures such as power plants should be stopped for reinforcement and difficult to reinforce and should be reinforced during operation. Especially, steel structures such as infrastructure and plants such as power plants may cause damage to the facilities during operation. Since braces cannot be used, both braces and stiffeners must be constructed using bolted joints.
