Abstract
A high-ductility shock-proof steel joint belongs to the technical field of multi-storey steel girder joints. The high-ductility shock-proof steel joint is characterized in that girders and posts are connected through all-welding; girder flanges are connected with post flanges through welds; girder webs and post flanges are connected through welds; and L-shaped profiled bars are respectively arranged at the upper parts and the lower parts of the girder flanges along the height direction and are connected to the girder flanges and the post flanges through bolts. After the joint area is damaged by an earthquake, particularly when the welds at the flanges of the ends of the girders totally craze and are out of work, the L-shaped profiled bars can have the functions of connecting and supporting.
Description
Technical field
The present invention's design belongs to Structural Engineering steel work technical field, especially many high-rise steel structure bean column node.
Technical background
Along with a large amount of constructions of many high levels, super highrise building, steel work is used more and more.Bean column node is normal in the structure design adopts full welding or the connection of edge of a wing welding-web bolt, and node area intensity, rigidity are bigger.But consider fully inadequately for geological process lower node district ductility, deformability and safety stock, the hidden danger that exists big shake effect lower node rupture failure to cause building destruction, collapse is not inconsistent with the seismic design principle of " no collapsing with strong earthquake ".How improving ductility, deformability, energy dissipation capacity and the node area safety stock of steel-structure beam-column node under geological process is problem demanding prompt solution in structural steel design, the construction.
Summary of the invention
Problem at steel-structure beam-column node ductility under-reserve in the prior art, the present invention proposes a kind of novel high tensility shock-resistant node, this node has improved ductility, deformability and the energy dissipation capacity of node under geological process on the basis that guarantees node area intensity, rigidity.
The technical solution adopted in the present invention is:
High tensility shock-resistant node of steel structure contains post and beam, it is characterized in that, wherein:
Post is made up of the post edge of a wing and column web,
Beam is made up of flange of beam and web,
Post adopts with beam and is welded to connect entirely: flange of beam is fixedlyed connected with the post edge of a wing by first weld seam at width, web is fixedlyed connected with the post edge of a wing by second weld seam in short transverse, in short transverse, the upper and lower of flange of beam is provided with L shaped steel and the 2nd L shaped steel respectively, and is connected on the flange of beam and the post edge of a wing with bolt.
Above-mentioned high tensility shock-resistant node of steel structure is characterized in that, is connected with bolt with described web, the post edge of a wing with L shaped steel in the both sides of described web along thickness direction.
Above-mentioned high tensility shock-resistant node of steel structure is characterized in that, the column web at described node place adopts the stiffening rib of welding to strengthen.
Above-mentioned high tensility shock-resistant node of steel structure is characterized in that, described stiffening rib is any one or its combination of level or diagonal.
Second technical scheme of the present invention is:
High tensility shock-resistant node of steel structure, contain post and beam, it is characterized in that, post adopts edge of a wing welding-web bolt to be connected with beam: flange of beam is fixedlyed connected with the post edge of a wing by the 3rd weld seam at width, web is connected with gusset plate by bolt in short transverse, and gusset plate is fixedlyed connected with the post edge of a wing by the 4th weld seam, in short transverse, the upper and lower of flange of beam is provided with L shaped steel and the 2nd L shaped steel respectively, and is connected on the flange of beam and the post edge of a wing with bolt.
Above-mentioned high tensility shock-resistant node of steel structure is characterized in that, the column web at described node place adopts the stiffening rib of welding to strengthen.
Above-mentioned high tensility shock-resistant node of steel structure is characterized in that, described stiffening rib is any one or its combination of level or diagonal.
Beneficial effect: (1) is after geological process lower node district destroys, especially after beam-ends edge of a wing weld seam ftractures fully and deactivates, L shaped steel can play and connect and supporting role, still keep certain rigidity and bearing capacity, improve deformability, ductility and the energy dissipation capacity of node, guarantee not occur because the building that the fracture of node causes collapses.
(2) by adopting the L shaped steel of different model, perhaps on shaped steel, replenish structures such as welding stiffening rib and handle, can realize the different requirements of node strength and rigidity according to the design and construction condition.
