2. Description of the Related Art Conventionally, a brace has been installed so as to be inclined in a space between a column and a beam of a steel frame structure to perform a reinforcing function. FIG. 6 shows a brace 1a in an existing steel frame structure, for example, and the brace 1a is formed by welding channel-shaped members back to back. As shown in FIG. 5, the braces 1a are arranged in a space 4 formed by the columns 2 and the beams 3 with an inclination. Both ends thereof are respectively fixed to a gusset plate 5 provided at the corners of the column 2 and the beam 3 and a gusset plate 6 provided at the center of the beam 3. When an external force such as an earthquake acts on the steel frame structure having the above structure, the brace 1a expands and contracts to resist the external force and exert a reinforcing action.

When a horizontal force due to an earthquake or the like acts on a steel frame structure using the conventional braces 1a and 1b shown in FIGS. 5 to 8, the horizontal force is below the elastic limit. Has almost no damping effect. That is, the relationship between stress and strain is linear in the tensile and compressive directions, and hysteresis damping does not occur. On the other hand, when the horizontal force exceeds the elastic limit, the brace members 1a and 1b buckle during compression to reduce the strength and exhibit unstable hysteresis characteristics, which may cause buckling failure.

With the above structure, when seismic force or the like acts, tensile and compressive forces act in the axial direction of the brace 1a. Although the entire buckling or partial buckling tends to occur in this portion, it is held by the mortar layer 13 and the encapsulated steel pipe 11. Further, slippage occurs due to the rock wool refractory layer 12, axial force is not transmitted to the mortar layer 13 and the encapsulated steel pipe 11, and stable hysteresis damping occurs in the brace 1a.
Due to this hysteresis damping, energy of external force such as seismic force is absorbed, vibration of the steel frame building can be suppressed, and strength and fire resistance can be improved.
