Lower flange is in sustained height, to prevent that it is excessive that the upper and lower edge of a wing of girder steel from producing for the steel pipe in Frame Joints of Concrete-Filled Steel Tube region
Normal tension and the effect of restraint for influenceing node region part steel pipe inner concrete.This node is used for diameter of steel tube and is more than or waits
In 1m situation.Compared with connections with exterior diaphragms, such a node has the advantages that construction is relatively simple, the saving interior space.
But inner ring steel plate is according to code requirement, its width needs reach diameter of steel tube 0.25 times, thus its exist construction inconvenience,
The shortcomings of steel using amount is high.Cut off in addition, the concrete in steel pipe is substantially all by inner ring steel plate, between concrete and inner ring steel plate
Carry out Transfer of Shear mainly by cohesive force and friction, even if reserved steam vent, can also have a strong impact on the construction quality of concrete, and then
Leave huge potential safety hazard.
