Abstract
The invention relates to a one-directional limiting performance-based joint of a steel structure. The one-directional limiting performance-based joint of the steel structure comprises a connecting steel plate, a reinforcing steel plate and shear connectors, wherein the reinforcing steel plate is tightly clung to the connecting steel plate through the upper section, and a semicircular hole is formed at the middle section; and the lower section is welded in a 'three-section' connecting mode; the shear connectors are welded at two sides of the connecting steel plate, and tightly clung to the upper end of the reinforcing steel plate; and a weld joint between the shear connector and the connecting steel plate meets the condition that the weld joint is in a perfect state under the seism at a relatively low level, and broken under the seism at a relatively high level. The one-directional limiting performance-based joint of the steel structure can bear relatively high axial force; the connecting steel plate can achieve the elastic connection in the plane, and has the capacity of bearing relatively high bending moment; the elastic connection can be achieved outside the plane of the connecting steel plate under the seism at the relatively low level, so that the joint can be kept in an elastic stage; and the performance-based connection can be implemented outside the plane of the connecting steel plate under the seism at the relatively high level, and the joint accesses a plasticity stage, therefore, more energy due to seism can be dissipated, and the safety of the structure can be ensured; and the one-directional limiting performance-based joint of a steel structure is simple to make up, convenient to manufacture, and can save the material.
Description
Technical field
The invention belongs to construction steel structure node technology field, relate in particular to a kind of steel work unilateral constrain performance-based connected node.
Background technology
The basic antidetonation basic intensity of the building target that China's " seismic design provision in building code " (GB50011-2010) stipulates is: when the frequently occurred earthquake that is lower than this area seismic fortification intensity affects, generally be not damaged or need do not repair and to continue to use, when being equivalent to the earthquake effect of this area seismic fortification intensity, may be damaged, but still can continue to use through running repair; When being higher than rarely occurred earthquake that this area seismic fortification intensity estimates and affecting, unlikelyly collapse or life-threatening heavy damage occurs.This just requires building structural element and node than the low water-mark earthquake time, remains on elastic stage; And when suffering the high levels earthquake, enter the plastic stage, certain deformation and failure occurs.When building suffers the high levels earthquake effect, can make the part secondary nodes produce larger plastic strain earthquake energy, thereby avoid main member and node generation heavy damage, so that malformation and destructiveness are controlled in the permissible range, guarantee integrally-built safety.Therefore, for the part secondary nodes of structure, can take specific form and necessary structure, make it under than the low water-mark earthquake, keep elasticity, suffer to enter the plastic stage under the high levels earthquake, can produce larger rotational deformation at specific direction.And, when structure is assessed and repaired after shake, might only need reparation shear connector or a small amount of weld seam can recover structural performance.At present, in the construction steel structure field, there is no the node of above-mentioned form.
Summary of the invention
The deficiency that can not in time enter the plastic stage in order to improve existing steel structure node under the high levels earthquake the object of the present invention is to provide a kind of simply constructed steel work unilateral constrain performance-based connected node.
For achieving the above object, the technical solution used in the present invention is: a kind of steel work unilateral constrain performance-based connected node, formed by junction steel plate 1, put more energy into steel plate 2 and shear connector 3, wherein: the steel plate 2 of putting more energy into is divided into upper, middle and lower segment, epimere and the junction steel plate 1 of the described steel plate 2 of putting more energy into fit tightly, described stage casing of putting more energy into steel plate 2 has semicircle orifice, the hypomere of the described steel plate 2 of putting more energy into and junction steel plate 1 welding; Shear connector 3 is welded in junction steel plate 1 both sides, and fits tightly in steel plate 2 upper ends of putting more energy into; During use, junction steel plate 1 two ends respectively with two steel Member Weldings.
Among the present invention, described shear connector 3 satisfies with the weld seam of junction steel plate 1: intact under than the low water-mark earthquake, rupture under the high levels earthquake suffering.
The invention has the beneficial effects as follows: node can be realized the Performance Design target, can bear larger axial force; Can realize in the junction steel plate plane that elasticity connects, and can bear larger moment of flexure; Under than the low water-mark earthquake, can realize outside the junction steel plate plane that elasticity connects, and guarantees that node is in elastic stage; Under the high levels earthquake, can realize outside the junction steel plate plane that performance-based connects, node enters the plastic stage, consumes to shake more energy, guarantees structural safety; Simple structure, easy to make, economical with materials.
Description of drawings
Fig. 1 is front elevation drawing of the present invention.
Fig. 2 is the I-I sectional view of Fig. 1.
Number in the figure: 1 is junction steel plate, and 2 are the steel plate of putting more energy into, and 3 is shear connector.
The specific embodiment
Further specify by reference to the accompanying drawings the present invention below by embodiment.
Embodiment 1: as depicted in figs. 1 and 2, the present invention is comprised of junction steel plate 1, put more energy into steel plate 2 and shear connector 3.During use, junction steel plate 1 two ends respectively with two steel Member Weldings, the steel plate 2 of putting more energy into adopts epimere to fit tightly with junction steel plate 1, open semicircle hole, stage casing, " syllogic " connected mode of hypomere welding.2 pairs of junction steel plate 1 deformity out of plane of steel plate of putting more energy into have certain effect of contraction, can prevent under the larger load flexing outside junction steel plate 1 plane.Node can realize that in junction steel plate 1 plane elasticity connects.Under than the low water-mark earthquake, shear connector 3 can effectively prevent junction steel plate 1 and the steel plate 2 epimere generation relative slidings of putting more energy into, and can realize that outside junction steel plate 1 plane elasticity connects, and guarantees that node is in elastic stage; Under the high levels earthquake, shear connector 3 is cut off with the weld seam of junction steel plate 1, relative sliding can occur in junction steel plate 1 and steel plate 2 epimeres of putting more energy into, node has certain turning power in junction steel plate 1 plane, can realize that performance-based connects, and entering the plastic stage, the sliding friction of the rotation of node and junction steel plate 1 and steel plate 2 epimeres of putting more energy into can consume more seismic energy.
