steel girder segment energy dissipation structure connected column which requests?

Guangzhou Steel tells you: steel girder segment energy dissipation structure connected column which requests?

Link beam connection with a rigid frame column nodes, connected with the general framework slightly different pillars.
When energy beams and column connections, its length should not be greater than 1.6M1p / Vb, energy beams between the flange and the webs between the link beam and column flange or flange (when link beam and column web connections) should selection groove full penetration butt welds, fillet welds should be used between the web and post-energy beams instead of bolting, due to slip the bolts will affect the ductility and energy dissipation capacity.
Carrying Capacity of fillet welds shall not be less than the axial bearing capacity web link beam, shear capacity and flexural capacity. Guangzhou Steel
