Protector management responsibilities, establish and improve various protection management systems, strengthen the protection awareness of each employee, complete pre-shift protection education and protection disclosure, and special work certificates. BRB buckling restrained brace is now particularly outstanding in the series of shock absorption products.
It is an indispensable and important product in shock absorption construction. Its role greatly reduces the unsafety caused by earthquakes. BRB buckling restrained brace (Buckling Restrained Brace, BRB) Constrain the lateral deformation of the steel support core through the outsourcing restraint structure.
The buckling of the steel support core material under compression is avoided, so that the support member can achieve material yield without buckling under axial tension and compression, and the material properties of the steel support core material are fully utilized.
Due to the above-mentioned stability China Seismic Isolation Device For Earthquake problems of the pressure rods in the general bending support, the ultimate bearing capacity of the general support under the action of axial pressure is generally stable.
And in general, the critical bearing capacity of components controlled by stability is much smaller than the limit value of section bearing capacity controlled by material strength, which is a schematic diagram of the general support's mechanical mechanism under the action of axial force and its Haohui curve.
It can be seen that because the general support is prone to instability when it is under compression, the compressive bearing capacity of the support is far from the compressive bearing capacity calculated according to the material strength, the tension-compression hysteretic curve of the component is asymmetrical, and the energy dissipation capacity is poor .
