Description
Technical field
The utility model relates to the building building technology field, especially a kind of reaming type steel-structure beam-column node that connects through end plate.
Background technology
Good ductility is the key factor that guarantees that structure does not collapse and destroys under severe earthquake action, and the ductility of node is a key factor that influences structural entity ductility.Before the Northridge of the U.S. in 1994 (Bei Ling) earthquake, it is the form that the steel framed structure beam-column connection generally adopts that the bolt weldering connects (edge of a wing welding, web bolt connect).Yet the slope of Japan earthquake centre celestially the Northridge of the U.S. in 1994 (Bei Ling) earthquake and 1995; Many destruction has taken place in the steel frame that once was considered to have the good resistance shock stability, wherein most brittle fractures (being the welding position brittle destruction af-ter) that destroy to beam column bolt weldering connected node place.In order to improve the ductility of connected node, the shake back U.S., Japan and other countries have carried out number of research projects to the anti-seismic performance of steel-frame beam column jointing gusset and ductile performance etc., have proposed multiple improved novel joint form.The research thinking basically identical of this type novel joint all is that girder steel end plastic hinge is moved on to outward on the beam of cylinder certain distance, thereby avoids the node brittle destruction af-ter, reaches the seismic design principle of " the weak member of strong node ".The difference of moving form according to plastic hinge outward can be divided into two big types with it: one type is weakening type node, like dog bone type node (cross section weakening is carried out near the node place in the bottom flange on beam) and girder steel root web open cell type node; Another kind of is reinforced node, like haunch type node, expansion aerofoil profile node, cover-plate type node etc.Yet show according to existing result of study: weakening type node makes load bearing beam power decrease to a certain extent; And the attachment weld of beam column edge of a wing root remains the weak location of weakening type node, and weldquality directly has influence on giving full play to of node ductility; And reinforced node be owing to can increase the weld seam of plate in original welding node zone, thereby causes connecting portion residual stress situation to become even more serious, particularly when weldquality is not high; Not only might be able to not improve the ductility of node but also can aggravate node brittle destruction af-ter (Wang Yan, Yu Yousheng, Wang Yue; Liu Xiuli. steel frame edge of a wing weakening type and expansion aerofoil profile node Study on behavior. mechanics and practice; 2010. 32 (1): 46-53.

[3]; Yang Na; Yang Qingshan. the edge of a wing weakens the performance study summary [J] of structural steel frame bean column node. engineering mechanics, 2004,21 (1): 61-66.).In addition, above-mentioned plastic hinge moves the type node outward and also has shortcomings such as shake back maintenance difficult or maintenance cost costliness (because this moment, serious deformation took place girder steel).
Utilizing the Frictional Slipping of friction-type high-strength bolt in oval bolt hole to improve node ductility is a kind of brand-new research thinking.People (Ma Renyues such as professor Ma Renyue of Tongji University; Yang Yang; Chen Qiaosheng etc. slotted hole modification property high-strength bolt node anti-seismic performance experimental study [J]. building structure journal, 2009,30 (1): 101-106) this thinking is applied to the steel beam splicing place (as shown in Figure 1) with the beam column of steel structure rigid joint of cantilever beam section; And applied for relevant patent (patent No.: 200820150748.X, 200810040509.3).The slotted hole of this node is arranged on the jointing positions of the girder steel edge of a wing and web; And the girder steel root still is to adopt weld seam to connect with being connected of steel column; Therefore under the rarely occurred earthquake effect; When the slewing area at steel beam splicing place exceeds its limit turning power, still have the welding brittle fracture that may cause girder steel root and steel column.
In order to remedy the deficiency of present existing steel structure bean column node, the utility model provides a kind of reaming type steel-structure beam-column node that connects through end plate.
