Description

[0001] The present invention relates to a buckling restraint brace with an assembled precast concrete reinforcement,

The present invention relates to a non-buckling bridge, particularly since a pre-cast concrete with a reinforcing material is preformed in a factory and assembled with a core material, there is no manufacturing error, so that the spacing dimension between the core material and the stiffener is stabilized, Stabilized and easily assembled precast concrete reinforcement material which is easy to construct on site.

Generally, a braced frame has a relatively high stiffness and strength, which is advantageous in resistance to horizontal loads such as earthquakes and winds. Thus, a braced frame is an excellent seismic element and can control damage caused by excessive horizontal displacement As a structural element.

However, the braced frame does not exhibit a large resistance effect against the seismic load because the buckling occurs when the ultimate load greater than the design seismic load is applied, so that the stiffness and the strength are sharply reduced and the energy dissipation is also reduced due to unstable behavior There is a problem in that the bracing and the brittle fracture of the joint occur due to the repeated load.

Particularly, in the case of the center braced frame, unbalance force acts on the beam due to the imbalance in force between the tensile bracing and the compressive bracing after buckling of the compression bracing. The layer which can not support the unbalance force has a great problem in structural stability such that the damage is concentrated and formed into a soft layer.

Buckling Restrained Braces (Buckling Restrained Braces) have been proposed to solve the buckling problems of the above braces. The non-buckling dam is proposed to cause inelastic deformation when subjected to a large earthquake load. Normally, as shown in Fig. 1 (a), a steel pipe 12 or a filler (mortar, concrete, etc.) As shown in FIG.

The buckling buckle has a merit that it can dissipate large energy in case of earthquake by preventing sudden strength deterioration due to buckling when compressing existing steel buckets, minimizes damage of other structural elements, concentrates damage to buckling buckets, It can be replaced after the earthquake. In addition, the strength and stiffness of the leaning brace can be easily adjusted to provide flexibility in structural design, and the behavior for inelastic analysis can be easily modeled.

As shown in FIG. 2, the type of the non-buckling bird is divided into three regions, ie, a constraint-yielding region, a constraint non-yielding region, and an unconstrained non-yielding region.

The restrained yielding section is a section yielding from the non-buckling bird, which requires stable hysteresis in the plastic zone after yielding under repeated loads such as earthquakes. Therefore, a material having high ductility is used. Buckling is suppressed by the reinforcing material, do. In addition, the constraint non-yielding section is a part connecting the unconstrained non-yielding section and the constraining yielding section, and is mainly composed of a cross section, and a reverse space exists for the core to move within the stiffener. And, the unconstrained non-yielding section exists to connect the non-buckling bird to the joint, and the shape of the joint is generally composed of bolt joint, pin joint, and weld joint.

However, in the conventional buckling buckets, the reinforcing material is a steel tube, and the concrete or mortar is filled in the reinforcing material. Such a filling type reinforcing material has a problem in that when the concrete is poured, Is unstable, the hysteresis behavior of the core due to the filling of the concrete at the cross-section of the core is unstable, and the detail for joining the stiffeners is not filled tightly.
