Ductility steel-structure beam-column node and its construction method, it is adaptable in the higher building structure of seismic fortification intensity.
Background technology
Good ductility and energy dissipation capacity be ensure structure meet with severe earthquake action when do not collapse destruction it is crucial because
Element, and the mechanical property of node is to influence one of key factor of overall structure anti-seismic performance.In the northern ridge earthquake in the U.S. and day
Before this Osaka-Kobe earthquake occurs, engineering circles are to steel-structure beam-column node mainly using all-weld joint or edge of a wing welding, web
Weld seam after bolt connection etc., but shake in these nodes there occurs brittle fracture.To improve the performance of connecting node, China, U.S.
State and Japan and other countries expand substantial amounts of research work to steel structure node, and propose the node connection side of diversified forms
Formula.Currently, the ductility using the bean column node of end plate connection is preferable, but its energy dissipation capacity is limited, and is still adopted between end plate and girder steel
With solder design, it is equally possible to occur brittle fracture；Using dog-bone joint（Weakened on beam-ends at lower flange）It can make
Destruction occurs in beam-ends, and meets the antidetonation principle of the weak component of strong node, but the weakening edge of a wing can reduce the bearing capacity of structure；Adopt
The bearing capacity of node can be ensured with reinforced node, but main use is welded to connect between plate, it is impossible to increase the ductility of node,
And aggravate the brittle break of node.
