Description
Technical field
The utility model relates to a kind of new section steel beam post syndeton, relates in particular to a kind of being applied in and is specially adapted to the set up defences new section steel beam post syndeton of earthquake zone of high earthquake intensity in the technical field of structural engineering.
Background technology
Steel work has the intensity height, from heavy and light, series of advantages such as anti-seismic performance is good, speed of application is fast, ground cost saving, area occupied is little, industrialization degree is high, good looking appearance, compare with concrete structure it be environment-friendly type and can utilize once more, also be the structure that is easy to industrialization.Connected node between the Liang Yuzhu is the critical component that guarantees beam and post collaborative work, forms structural entity.In many high-rise steel structure framework, it is that flange of beam utilizes high-strength bolt to be connected with post butt welding, web with pillar that typical Liang – post connects.Past thinks that always Gai has good seismic resistance by Liang – post bolt weldering mixed node, yet, in slope god (the Hyogoken – Nanbu) earthquake of Bei Ling in 1994 (Northridge) earthquake and nineteen ninety-five, though adopt hundreds of steel buildings of this joint structure not collapse, serious brittle fracture occurred at position of joints.Researchers improve traditional bean column node when seeking its destruction reason, have proposed the strong joint form of ductility and energy dissipation capacity.Improved major measure has: connecting portion is strengthened, beam section is weakened, improve fan-shaped corner cut structure, save the welding operation hole web and post welding etc.Although above-mentioned improved bean column node shows superior anti-seismic performance in the laboratory, the formation plastic hinge provides structure required ductility in the Vierendeel girder but because its seismic design thought is based on, use the actual engineering of these nodes if be damaged, repair difficulty relatively.
Because lower flange of girder edge and the field welding between the pillar that the quality of Liang – post node junction is difficult for guaranteeing are to cause node the inducement of brittle fracture to occur, therefore, the complete bolted bean column node of no field welding is examined closely again.Adopt the full bolt De Liang – post node usually need be by means of connector, typical connector has T-connecting piece, angle steel and end plate etc.The full bolt connected node of Liang – post ductility is better, energy dissipation capacity is strong, anti-seismic performance is superior.According to connecting portion and be connected relation between the anti-bending bearing capacity of beam, help strong connection and be connected two classes with part intensity connecting to divide.Wherein, the supporting capacity that complete strong connection is a connecting portion is higher than the bearing capacity that is connected beam, forms plastic hinge during destruction of a node on beam.Part intensity connect be the supporting capacity of connecting portion less than the bearing capacity that is connected beam, connector at first destroys.Reparation and welding connection node after the complete strong bolt connected node that connects destroys are similar, relatively difficulty.The bolted repair amount of part intensity is different and difference to some extent according to the connection adopted: because end plate and beam-ends welding, the node that adopts end plate to connect is repaired difficult; All adopt bolt to be connected between T-connecting piece and angle steel and the agent structure beam column, connect behind the destruction of a node change relatively easy.But the connector at position, beam top flange still needs to remove earlier near the steel concrete of connector owing to be embedded in the concrete during replacing.
Summary of the invention
For fear of above-mentioned existing in prior technology weak point, the utility model provides a kind of set up defences new section steel beam post syndeton of earthquake zone of high earthquake intensity that is particularly suitable for.This structure can effectively prevent brittle fracture, has good ductile fracture feature, and can be widely used in earthquake zone, especially high earthquake intensity and set up defences in the structure of earthquake zone, and easy construction, be convenient to shake the back and repair.
The utility model provides a kind of new section steel beam post syndeton, comprise that vertical H steel column and its end are vertically connected on the H section steel beam on the H steel column side wing, it is characterized in that: described H section steel beam web and H steel column side wing link are realized being connected through a reinforced company's fishplate bar that fits with H section steel beam web and the high-strength bolt that runs through reinforced company's fishplate bar, described reinforced company fishplate bar welds mutually with H steel column side wing, the link both sides of described H section steel beam bottom side wing plate are respectively through a T type junction plate and run through high-strength bolt and H steel column and realize that locking is connected, described T type junction plate is laterally placed, its vertical upper and lower side respectively through pad with run through the locking of high-strength bolt and H steel column side wing and be connected, the transverse plate of described T type junction plate is supported in the below of H section steel beam bottom side wing plate, and through running through high-strength bolt locking.
Compare with prior art, the beneficial effects of the utility model are embodied in:
1, can solve preferably traditional beam-column connection ductility deficiency, easily the problem of brittle fracture takes place;
2, can solve the problem that modified beam-column connection shake back is difficult for reparation preferably;
3 are connected bean column node with traditional full bolt compares, and destroys to concentrate on the connector of lower flange of girder edge, repairs simple relatively;
4, suitably reduced rotational stiffness constraint between the beam column, it is more reasonable that moment of flexure is distributed, and brings more economical design result;
5, the connected node construction is more convenient, and quality is easy to control;
6, utilize high-strength bolt to be connected by T-connecting piece between lower flange of girder edge and the post edge of a wing, web adopts high-strength bolt to be connected with scab on being welded on the post edge of a wing, center, beam top flange is as the center of rotation of connecting portion, the design of the supporting capacity of the T-connecting piece of bottom flange relatively a little less than, protect the beam column member and the connector at place, top flange in earthquake, to avoid damage with this;
7, between the edge of a wing of the T-connecting piece at lower flange of girder edge position and the post edge of a wing backing plate is set, the edge of a wing of T-connecting piece can be surrendered to positive and negative both direction generation moment of flexure, guarantee beam when positive and negative both direction rotates, the distortion of connecting portion is all provided by the distortion at lower flange of girder edge position.Plastic strain and destroy the T shape part concentrate on lower flange of girder edge position reaches the purpose that the protection main body is avoided damaging, connected node is convenient to repair.
