Description

A kind of assembled band frame ribbing steel plate shear force wall
Technical field
The present invention relates to a kind of novel assembled band frame ribbing steel plate shear force walls, belong to technical field of structural engineering.
Background technology
Steel plate shear wall structure is steel plate shear force wall to be applied in building by Nippon Steel Corporation the 1970s, from And a kind of novel lateral resisting structure system to grow up, the past is over forties years, about steel plate wall as main level anti-side The experimental study and numerical analysis of power system disclose its unique performance, including larger elastic initial stiffness, large deformation energy The hysteretic characteristic etc. of power and good plastic property, stabilization.Up to the present, the whole world uses steel plate shear force wall as main anti-side The building of power component has tens of buildings altogether, is mainly distributed on the Areas of High Earthquake Intensities area such as North America and Japan.Steel plate wall has become one kind The very high-rise Lateral Resistant System with development prospect is particularly suitable for high intensity Zone building.
Since its is generous bigger local buckling just occurs when lateral force is smaller for traditional thin plate shear wall, and with side Gradual increase to power forms pull strap in steel plate wall diagonal, and the design principle of stiffened steel plates wall is to utilize different form Ribbed stiffener delay the buckling of steel plate, improve the ultimate bearing capacity and ductile performance of steel plate.To sheet metal wall, setting can be passed through Ribbed stiffener is to improve its stress performance and ductility.Although having good economic benefit, it easily sends out traditional thin steel plate shear wall Raw buckling fails in stress and frame column is caused to bear extra load, and applies man-hour requirement site welding, and speed of application is slow.Cause This can both improve the anti-side rigidity of steel plate with frame ribbing and fabricated steel plate shear force wall, and steel plate is allowed to be maintained at as far as possible Work, improves the anti-seismic performance and energy dissipation capacity of shear wall, while reducing cost, shortens the construction period, increase economic efficiency in plane.
Invention content
The present invention proposes a kind of novel assembled band frame ribbing steel plate shear force wall, it is intended that overcoming Bao Gang The shortcomings that plate shear wall cannot give full play to the intensity and ductility of steel because of premature flat out-of-plane buckling improves steel plate shearing The Outside-plate stabilizing of wall, ultimate bearing capacity and anti-side rigidity have given full play to the advantage of steel;Using assembled module, institute Have component can prefabrication, it is cost-effective, shorten the construction period.
Since its is generous bigger when smaller by lateral load local buckling just occurs for traditional thin steel plate shear wall, And pull strap is formed in steel plate diagonal with the gradual increase of lateral load, along with larger out-of-plane deformation, when When external load acting in opposition, pull strap, which is reversely pressurized, can will no longer provide rigidity.And outer load reversal act on during, due to Once larger lateral deflection deformation occurred under higher level's load, the compressive region of steel plate wall will be undergone " open and flat " when being transited into pulling force zone Process, until the formation of reversal interlocking relay band.In this course, steel plate can not bearing load, structure only undertakes by frame beam column External load, increase pillar stablizes burden.Therefore the setting for shearing wall frame and ribbed stiffener, on the one hand controls steel plate buckling Larger deformity out of plane afterwards provides sidewise restraint and vertical constraint, avoids steel plate wall when reversed external load acts on Failure procedure, improve the anti-side rigidity and ductile performance of structure entirety;On the other hand, since shear wall only connects with Vierendeel girder It connects and is not connected to frame column, shear wall surrounding punches flexibly, so preferably lateral resistant member can be used as to be applied to more Tall Steels In structure.
Assembled proposed by the present invention with frame ribbing steel plate shear force wall is changed to the non-assembling steel plate shear wall of tradition Into on the one hand controlling the Outside-plate stabilizing of steel plate using the double constraints of shearing wall frame and ribbing, improve conventional steel plates The defect of the easy buckling of shear wall, improves the lateral resistant ability of steel plate shear force wall, simultaneously because above-mentioned assembled band frame ribbing steel The out of plane stiffness of plate shear wall is very big, can effectively control transport, installation and using the deformity out of plane in engineering, keep The firm safety of steel plate;On the other hand, it is not connected to frame column since shear wall is only connect with Vierendeel girder, shear wall surrounding punches Flexibly, so preferably lateral resistant member can be used as to be applied in multi and tall steel building;And all components of the present invention all may be used To be processed and install in factory, then it is transported to building site and is assembled, avoid site welding operation, use manpower and material resources sparingly, It shortens the construction period, reduces cost.
A kind of assembled band frame ribbing steel plate shear force wall, which is characterized in that including embedded steel plate 1, frame columns 2, frame Column partition board 3, frame columns connecting plate 4, connecting plate 5, horizontal ribbed 6, vertical floor 7, Vierendeel girder 8, frame column 9 and frame column partition board 10;Horizontal positioned frame columns partition board 3 and the frame columns connecting plate 4 placed vertically are both secured to frame columns or more, each frame There are one frame columns partition boards 3 and frame columns connecting plate 4 above column;There are one frame columns partition board 3 and frames below each frame columns Column connecting plate 4;Frame columns connecting plate 4 is bolted with connecting plate 5;Integral prefabricated, the transverse direction with frame columns and embedded steel plate 1 Floor 6, vertical floor 7 are all made of rectangle floor and are fixed on 1 unilateral side of embedded steel plate;The embedded steel plate 1 and frame columns 2, frame Column partition board 3, frame columns connecting plate 4, horizontal ribbed 6, the whole shear wall module of 7 prefabricated composition of vertical floor, wherein the frame Column 2, frame columns partition board 3, frame columns connecting plate 4 are arranged symmetrically in 1 both sides of embedded steel plate;Above whole shear wall module Connecting plate 5 be fixed on 8 lower flange of Vierendeel girder;Connecting plate 5 is individually fixed in 8 upper limb of Vierendeel girder below whole shear wall module Edge;The connecting plate 5 and Vierendeel girder 8 are integral prefabricated;The connecting plate 5 is connect with whole shear wall module with high-strength bolt; The entirety shear wall module is not connected to frame column 9;The Vierendeel girder 8 is connect with the frame column 9;The frame columns partition board 3 use uniform thickness steel plate with horizontal ribbed 6, and same level is fixed in upper surface;The frame columns connecting plate 4 with it is interior Embedding steel plate 1 uses uniform thickness steel plate;The entirety shear wall module embeds steel plate 1 and plane where the contact surface of connecting plate 5 For plane where 8 centre of form of Vierendeel girder.
