BRB IntroConnection Type Test
A new type of shock-absorbing product that combines support and an energy-dissipating damper.The sleeve is used to provide restraint to the support core material and restrain the support from buckling under compression.
Ordinary braces will be buckled under compression, and their hysteretic performance will be poor under repeated loads. The Buckling Restrained Brace only connects the core plate with other components, and all the loads are borne by the core plate. The outer sleeve and the filling material only restrain the core plate from buckling under compression, so that the core plate can enter and yield under tension and compression. Excellent hysteresis performance.
On the one hand, the Buckling Restrained Brace can avoid the defects of the significant difference in the tensile and compressive bearing capacity of ordinary supports, and on the other hand, it has the energy dissipation capacity of a metal damper to keep the main structure within the elastic range. The application of buckling restraint supports can comprehensively improve the seismic performance of traditional support frames under moderate and large earthquakes.
1. The look-up table of appearance size takes the BRB appearance size as a square design;
2. Example: Yield capacity 4000kn, BRB length 4800mm, appearance size 350mm×350mm;
3. For products whose yield capacity or product length does not completely correspond to the data, the length can be determined by referring to similar data.

Bolted connection
The two ends of the Buckling Restrained Brace and the corresponding gusset plate are pre-opened with screw holes, and high-strength bolts are used to connect each component.
Advantages: high installation efficiency, low requirements for personnel, overall appearance, and moderate price.
Disadvantages: There are many factors affecting the installation angle, and the existence of errors makes the accuracy difficult to control, and the adaptability is the worst.

Welded connection
The Buckling Restrained Brace is connected with the gusset plates at both ends directly by butt welds.
Advantages: high installation flexibility, strong adaptability, economical price, high fault tolerance rate.
Disadvantages: Need to consider the residual stress caused by welding, which requires high welders' ability.

Pinned connection
The two ends of the Buckling Restrained Brace and the gusset plate need to be pre-opened with round holes, and each side is connected by a pin.
Advantages: the highest installation efficiency, lower requirements for workers, and the most beautiful overall.
Disadvantages: the most expensive price, high precision requirements, poor installation flexibility.
