Background
In the high-rise building design, the node connected by the beam column is the key in the design of the node of the high-rise building structure, the performance of the node directly influences the strength, rigidity, stability and other performances of the structure, and the condition that the beam part is weakened is also researched in the past, but the condition that the beam part is bent is often generated.
In the traditional joint design, a full penetration butt welding seam is often adopted, the advantages of beam-column joints are not exerted, the bending resistance bearing capacity of a beam cannot be well exerted, and the design principle of 'strong joint and weak member' in the anti-seismic design is not well exerted.
Disclosure of Invention
The utility model aims to solve the technical problem that a shear force wall steel is buckling restrained node even roof beam is provided, has avoided the side direction unstability of girder steel, has improved the nature of the dissipation seismic energy of node for the shock resistance improves greatly.
In order to achieve the above object, the utility model adopts the following technical scheme:
shear force wall steel is roof beam buckling restrained node even, including H shaped steel even roof beam, pre-buried square shaped steel, the concrete column, be equipped with pre-buried square shaped steel in the concrete column, the terminal surface rigid coupling end plate of H shaped steel even roof beam, end plate and pre-buried square shaped steel bolted connection, be close to the upper and lower flange plate of the H shaped steel even roof beam of end plate and be equipped with dog bone formula weakened area, be equipped with in the weakened recess of dog bone formula weakened area and weaken recess matched with backing plate, backing plate and weakened recess spot welding are connected, the outside of upper and lower dog bone formula weakened area is equipped with the apron respectively, the both sides of the web of the H shaped steel even roof beam that dog bone formula weakened area corresponds are equipped with the flute profile backplate respectively, pass through bolted connection between upper and lower flange plate of H shaped steel even roof beam and the flute profile backplate, be equipped with a plurality of stiffening rib in the notch of flute profile backplate, the apron covers dog bone formula weakened area completely with the flute profile backplate.
The cover plate and the groove-shaped guard plate have the same length.
The stiffening ribs are symmetrically arranged in the groove-shaped guard plates on two sides of the web plate of the H-shaped steel connecting beam, and the number of the stiffening ribs on each side is 2-4.
The groove-shaped guard plate is made of channel steel.
The surfaces of the H-shaped steel connecting beam, the groove-shaped guard plate and the cover plate which are contacted with each other are coated with an adhesive-free layer.
The non-adhesive layer is made of rubber.
Compared with the prior art, the beneficial effects of the utility model are that:
the cover plate is arranged outside the dog-bone type weakening area, the groove-shaped guard plate forms a buckling-restrained structure, and the phenomenon of buckling instability outside the steel plate plane, which is possibly generated at the positions of the beam flange and the beam web plate when the beam is stressed, is avoided. The seismic performance of the nodes is reduced, the hysteresis curve of the nodes also has the degradation phenomenon of rigidity and strength, and the out-of-plane rigidity of the delayed steel beam with the degradation phenomenon is reduced, so that the probability of generating out-of-plane integral buckling of the steel beam is improved. The buckling restrained device avoids lateral instability of the steel beam, improves the property of dissipating seismic energy of the node of the steel beam, and greatly improves the seismic capacity.
The profile steel is embedded in the concrete shear wall, and the concrete and the profile steel have the mutual constraint effect. On the one hand, the concrete is wrapped around the section steel, and the section steel is rarely subjected to local buckling before the member reaches the bearing capacity. On the other hand, the section steel has a restraining effect on the concrete of the core. Compared with the common shear wall, the shear wall has greatly improved bearing capacity.
