Abstract
The utility model discloses a porous steel structure beam column joint in beam -ends web area welds in the beam -column connection region, makes its rigid connection, is a whole with beam -column connection, being close to beam -column connection department at the web, opening a plurality of apertures and carry out web weakening, the consumed energy makes plastic failure at first take place herein, avoids brittle failure, improves the anti -seismic performance of structure, be close to beam -column connection department at the post web, add the stiffening rib, prevent stress concentration, improve the intensity of beam -column connection node, the web trompil is favourable to the construction, can make the pipeline conveniently pass through, has practiced thrift the resource, has improved the efficiency of construction.
Description
Technical field
This utility model is related to a kind of steel-structure beam-column node with porous for web plate.
Background technology
Steel construction has the advantages of light, fabrication and installation industrialization degree height of conducting oneself with dignity, plasticity good toughness, has a wide range of applications
Field.In building construction, there are substantial amounts of steel-structure factory building, nigh-level synthesis, large-span steel rack building, suspended-cable structure
Building etc.；Various forms of steel bridges are had on highway and railway；Head tower and steel mast are then widely used as electric power pylon, television broadcasting
Launching tower.At present, the development of Steel Construction In China building is very rapid, particularly can represent our national economic strength, science and technology
A series of building up of nigh-level synthesis of level, material technology and Building technology, steel construction in Chinese application and is sent out
New climax has been pushed in exhibition.
Show 50 years of future about research, China probably occur especially big, there is destructive earthquake, earthquake meeting
A certain degree of negative effect is caused to Chinese society and economic development.So we are necessary the property to steel-structure beam-column node
Can comprehensively be studied, and be researched and developed new ductile bean column node form, be strengthened the anti-seismic performance of bean column node, and in actual work
Apply in journey, reduce casualties in earthquake for the China and economic loss.
Strong column and weak beam is a structuring concept proposing from seismic design of structures angle.It is exactly that post does not break prior to beam
Bad, because beam destroys belongs to component damage, be locality, pillar destroys and will jeopardize the safety of total --- may be whole
Body collapses, and consequence is serious.So post to be ensured more " relative " safety, therefore want " strong column and weak beam ".The mentality of designing of weakening type node
It is by weakening to the beam of certain distance at beam-to-column joint, promoting plastic hinge to occur in beam weak point and expand
Exhibition, greatly reduces the stress concentration phenomenon of node region, it is to avoid node crack too early, to reach Ductility Design purpose,
Weak point is equivalent to the effect serving electric fuse.Because plastic hinge occurs and extends so that longer in the weak point of beam
One section of beam almost simultaneously enters plasticity, that is, be truly realized Ductility Design, has given full play to the plastic property of steel, has greatly increased
The energy-dissipating property of structure.
Utility model content
This utility model purpose provides a kind of steel-structure beam-column node with porous for web plate.
This utility model uses for reference construction, the loading characteristic of analysis node and the Energy Dissipation Mechanism of domestic and international ductility joint, proposes
A kind of novel joint constructs thinking: it is subjected in beam-to-column joint region so as to just connect, beam-to-column joint is whole for one
Body, enhances the stability in the large of structure；In web at beam-to-column joint, open multiple apertures and carry out web weakening, consume
Energy, makes plastic failure betide this first, it is to avoid brittle break；In column web at beam-to-column joint, set up ribbed stiffener, prevent
Only stress concentration, improves the intensity of beam-column connection；Web holes are favourable to construction, and pipeline can be made easily to lead to
Cross, saved resource, improve the efficiency of construction.
The beneficial effects of the utility model: this utility model is simple and practical, on the basis of common welded steel structure
Perforate weakening is carried out to web, realizes plastic hinge, improve the deformability of node, effectively improve bean column node
Anti-seismic performance, simultaneously in column web at beam-to-column joint, sets up ribbed stiffener, prevents stress concentration, improves beam-column connection
Intensity, also can improve the shear resistance of node.Web holes can make pipeline easily pass through, and to convenient construction, reduce and build
Build floor height to be beneficial to.
Brief description
Fig. 1 this utility model framework composition node drawing；
In Fig. 1,1 steel column；2 girder steels；3 transverse stiffeners；4 small sircle holes.
Specific embodiment
Shown in Fig. 1, it is a kind of steel-structure beam-column node with porous for web plate,
It is subjected in beam-to-column joint region so as to just connect, beam-to-column joint is an entirety；Close in web
At beam-to-column joint, open multiple apertures and carry out web weakening, consumed energy, make plastic failure betide this first, it is to avoid fragility is broken
Bad；In column web at beam-to-column joint, set up ribbed stiffener, prevent stress concentration, improve the intensity of beam-column connection.More than
Described be only preferred embodiment of the present utility model, not in order to limit this utility model, all of the present utility model spirit and
Within principle, any modification, equivalent substitution and improvement made etc., should be included within protection domain of the present utility model.
Claims (3)
1. a kind of steel-structure beam-column node with porous for web plate, it is characterised in that being welded in beam-to-column joint region, makes
