Description
Technical field
The invention belongs to technical field of buildings, exactly is the outer annular-stiffer formula steel work abnormity space nodes of a kind of beam position skew.
Background technology
Steel work is widely used in building field because of its series of advantages, more becomes the main building type of high level or super highrise building.And bean column node is as the joint of each member of steel framed structure, destruction or local collapse that its destruction will cause structure generation to be difficult to recover, even cause the Total Collapse of structure.Therefore bean column node is one of link of most critical in the structural steel design, it is one of key factor of the whole steel frame performance of impact.In the steel pipe column with rectangle section of using at present morely, because directly being welded on the steel column lateral surface, crossbeam make the steel column tube wall bear huge pulling force and shearing from crossbeam, this can cause the gross distortion of steel column tube wall, even destroy, traditional solution is horizontal internal partition to be set improve its rigidity and mechanical strength in the weld steel column.But diaphragm was default according to building storey height in this method required, if the absolute altitude error appears in the job site or absolute altitude is made mistakes, then diaphragm and node misplace in the post, do not have Expected Results.In addition, in the joint reinforcing of steel work, the corresponding position is difficult to add diaphragm in steel column, and traditional reinforcement means, such as haunched beam, cover plate etc., though can to a certain degree improve ultimate bearing capacity of joints, but can not effectively solve the internal force transmission between the beam, still have certain potential safety hazard.Based on the problems referred to above, this paper inventor has carried out further further investigation to the outer power transmission node of the Novel pole that proposes according to actual stabilization works, this is a kind of novel without inner diaphragm joint, realizes power transmission outside the post by outer annular-stiffer plate and parallel webs are set at Nodes.
Welding is the important processing technology of manufacture of steel structure industry.It is a kind of accurate, reliable, low-cost, and is the method that adopts the high-tech connecting material.Along with the development of China's electronic technology, computer microelectronics information and automatic technology, promoted the development of welding automatization technology.Particularly the introducing of the monotechnicss such as Numeric Control Technology, Flexible Manufacturing Technology and the information processing technology has promoted the revolutionary development of welding automatization technology.The digital welding machine, the digitlization control cap technology that represent automatic welding technique had already emerged and had come into the market steadily.The national large foundation engineerings such as Three Gorges Projects, West-East National Gas Transmission Project, aerospace engineering, Marine engineering have effectively promoted advanced welding particularly development and the progress of welding automatization technology.China's welding industry is progressively moved towards " efficiently, automation, intellectuality ".The assurance that the development of these technology is strong method of attachment and the intensity of steel structure member.
Complicated various along with building types, the reinforcing mode that solves abnormal joint in the steel work becomes further important, and since steel work have Bearing Capacity Per Volume of Bored-cast high, produce that easy for installation, short construction period, anti-seismic performance are good, reconstruction and remove easily, the recovery and reuse rate high of material, steel work will be more extensive in the application of China.
Summary of the invention
Along with reaching its maturity of China's steel work development is perfect, abnormal joint constantly occurs in large scale structure and labyrinth, and quadrate steel pipe column H section steel beam spatial special node is widely applied in steel work.If directly it is welded, two kinds of failure modes can occur: the first failure mode is owing near the unstability that is squeezed of the beam compression flange the bean column node causes the frange plate flexing to lose bearing capacity; The second failure mode is for the square tube post that internal partition is not set, and this local deformation of unevenness maximum position is in the position that is connected with bottom flange on the beam.The web of beam-ends link position beam own is connected on the edge of a wing of post, is out of shape outward so that the frange plate of pillar easily produces face, and the web by beam just becomes a difficult problem to pillar transmission moment of flexure like this.Thus, be that the situation of H tee section is compared with pillar, the anti-bending bearing capacity of beam-ends reduces.Bottom flange and post frange plate link position have been born most moment of flexure on the beam like this.Therefore, this position column frange plate side direction deformation of unevenness will reduce anti-bending bearing capacity greatly.When outer distortion acquires a certain degree face to face, bean column node will be lost bearing capacity and destroy.New Types of Beam column Connections of the present invention need to not cut off post jamb at Nodes internal partition is set, and has realized guaranteeing the outer power transmission of post and the successional requirement of post jamb of Nodes, can realize being rigidly connected of bean column node simultaneously.Because the method for attachment of this kind Types of nodes is reliable, job practices is simple, so it can better be applied to engineering reality.The invention belongs to a kind of novel steel-structure beam-column node tectonic type, because horizontal beam and column lateral surface directly welds, can make post jamb bear huge pulling force and shearing, cause the post jamb gross distortion, simultaneously in order to guarantee pillar in continuity and the easy construction of Nodes, to Node configuration outer annular-stiffer plate.For guarantee power transmission continuously, at the outer ring plate of beam position skew place parallel webs is set.This node is realized the outer power transmission of post, makes stress transfer arrive outer annular-stiffer plate place, thereby the yield strength of node and ultimate bearing are improved greatly, and distortion also reduces, and has greatly strengthened the bearing capacity of node.Simultaneously, this Types of nodes constructability is fit to be applied to Large Scale Steel Frame structure and staggered floor construction.
Technical scheme is as follows:
The pillar that requires according to " strong column and weak beam, the weak member of strong node " among " seismic design provision in building code " GB50011-2010 does not destroy prior to beam, and the bearing capacity of node should be higher than and is connected member.Realize transmission power and moment of flexure by the parallel webs between outer annular-stiffer plate and dislocation ring flat-plate, flange of beam near Nodes adds outer ring plate to this node in the post outside, with the internal force that the transfer beams edge of a wing is transmitted, make the internal force transmission between the beam walk around the outer power transmission of pillar realization post.This new interior power transfer mode can arrive outer annular-stiffer plate place with most of stress transfer, thereby so that the yield stress of node and ultimate bearing capacity improve greatly, has better met standard about the requirement of " strong column and weak beam, the weak member of strong node ".
Advantage of the present invention and beneficial effect:
1. adopt the reinforcing mode of outer annular-stiffer plate so that quadrate steel pipe column has avoided cutting off the situation of the built-in internal partition of post jamb, guaranteed globality and the continuity of pillar.2. the novel outer annular-stiffer formula of this kind abnormity space nodes inheritance and development the design theory method of current ordinary node form nodes domains, and realized being rigidly connected of bean column node.3. this novel special-shaped space nodes has preferably that supporting capacity and anti-seismic performance make node have good ductility and anti-seismic performance, and good energy dissipation capacity has node and guarantees requirement energy-saving and cost-reducing and the low-carbon environment-friendly building.4. solved in the current complex steel structure system the special requirement on building space and the plane figure.5. be transported to again engineering site after this node component is processed by factory's batch production and carry out assembly welding, effectively raise production efficiency, the reduction of erection time.Discuss by research, the beam column space nodes of the novel beam of this kind position skew has preferably ductility, supporting capacity and energy dissipation capacity.Can satisfy the instructions for use of bearing capacity, Practical Project that rigidity requirement is higher, for building leaves more safety stock.
