Description
Technical Field
The invention relates to a novel energy-consuming, buckling-restrained, light and high-strength double-corrugated steel plate shear wall with a built-in vertical seam energy-consuming steel plate connected at two sides, which is mainly used as a side-resistant and energy-consuming component in a modular unit of a modular steel structure and belongs to the technical field of structural engineering.
Background
One of the hotspots of the present engineering seismic research: how to reduce the irrecoverable damage of main bearing members and non-structural members of a building structure after an earthquake so that the structure can be quickly repaired and normally used after the earthquake. The energy dissipation component is arranged in the structure, so that input energy of an earthquake can be effectively dissipated, and deformation of the structure is mainly concentrated in the energy dissipation component.
The steel plate with the vertical joints is formed by forming the vertical joints at equal intervals in the middle of the steel plate shear wall, and the original whole flat steel plate is divided into strip belts with a plurality of long strips, so that the oblique tension belt is broken when the traditional steel plate shear wall is sheared, and each strip plate is borne in a stress state of a bent column. Therefore, the vertical seam steel plate shear wall converts the shear deformation of the steel plate shear wall into bending deformation, and the ductility of the steel plate is improved. Although the vertical-seam steel plate shear wall can solve the problem that a hysteresis curve of a traditional steel plate shear wall is pinched, the external deformation of the vertical-seam steel plate shear wall is obvious, and the ultimate bearing capacity of the vertical-seam steel plate shear wall is greatly reduced due to the fact that the stable tension belt bearing capacity of the traditional steel plate shear wall after buckling is destroyed.
By adopting the measure of covering the corrugated steel plates on the two sides of the vertical slotted steel plate, the out-of-plane deformation of the vertical slotted steel plate can be restrained to a certain extent, and the buckling of the steel plate is delayed; meanwhile, the closed section formed by buckling the corrugated steel plates can provide higher lateral resistance for the whole steel plate shear wall system, so that the defect of low ultimate bearing capacity of the vertical slotted steel plate shear wall can be overcome. Because the thickness of the corrugated steel plate is thin, the phenomenon that the steel plate is torn easily appears at the bolt connecting position of the two buckled corrugated steel plates under the action of the horizontal shearing force, and the vertical slotted steel plate arranged in the corrugated steel plate can also play a role in reinforcing the connecting position.
Disclosure of Invention
The invention aims to provide a double-corrugated steel plate shear wall which is stable in energy consumption performance, light in weight, high in strength, controllable in design parameters and applicable to connecting two sides of a modular steel structure module unit and is internally provided with a steel plate with a vertical seam.
The technical scheme of the invention is as follows:
the double-corrugated steel plate shear wall with the built-in vertical seam steel plates and the two connected sides mainly comprises three parts, namely the built-in vertical seam steel plates, trapezoidal corrugated steel plates on two sides of the vertical seam steel plates and an edge frame; the built-in vertical seam steel plate can be provided with vertical seams with different widths and different forms according to actual conditions and design requirements, and the periphery of the vertical seam steel plate is connected with the edges of the corrugated steel at two sides through welding seams; the corrugated steel plates are in a trapezoidal corrugated form, and the wave trough positions of the two corrugated steel plates are connected with the embedded vertical seam steel plate through high-strength bolts to form a complete embedded steel plate system; the edge frame is composed of an upper edge frame beam, a lower edge frame beam, a left edge self-contained side column and a right edge self-contained side column.
In the double-corrugated steel plate shear wall with the built-in vertical seam steel plates connected at the two sides, the vertical seam steel plates are vertically provided with through seams.
In the double corrugated steel plate shear wall with the built-in vertical seam steel plates connected at the two sides, the vertical seam flat steel plate is riveted with the corrugated steel plates at the two sides and is in the position of a wave trough and a wave crest, and the edge position of the vertical seam flat steel plate is connected with the edge of the corrugated steel plate through welding seams to form a complete embedded steel plate system.
In the double corrugated steel plate shear wall with the built-in vertical seam steel plates connected at two sides, the complete embedded steel plate system is directly inserted into symmetrical angle steels preset at the periphery of the edge frame and is reliably connected with the symmetrical angle steels through welding seams.
In the double corrugated steel plate shear wall with the built-in vertical seam steel plates connected at two sides, the symmetrical angle steel is connected with the upper and lower edge frame columns and the left and right self-contained side columns through bolts, and the symmetrical angle steel can limit the out-of-plane displacement of the shear wall to a certain extent.
In the double-corrugated steel plate shear wall with the built-in vertical seam steel plates connected on the two sides, different shear wall strengths and rigidities can be designed by changing the width and the arrangement form of the vertical seam and the section shape parameters of the trapezoidal corrugated steel plate, such as the wave trough section width, the wave crest section width, the wave amplitude, the inclined section inclination angle, the steel plate thickness and the like, so that different yield loads and corresponding yield displacements thereof are realized, and the design with controllable parameters is realized.
The invention has the beneficial effects that:
(1) the measure of arranging the vertical seam steel plate in the trapezoidal corrugated buckling corrugated steel plate is adopted, so that the out-of-plane deformation of the arranged vertical seam steel plate can be limited to a certain extent, and the bending deformation can be fully utilized to consume energy;
(2) the closed section formed by the trapezoidal corrugated steel plates and the vertical seam steel plates which are buckled on the two sides in a butt joint mode can improve the bearing capacity of the whole steel plate shear wall system, effectively overcomes the defect of poor ultimate bearing capacity of the vertical seam steel plates, and meanwhile, the out-of-plane buckling deformation of the steel plate shear wall system can be relieved to a certain extent due to the trapezoidal corrugated steel plates on the two sides;
(3) the flat steel plate with the vertical seam is arranged between the two wave forms, so that the strength of the connecting part is improved, and the early tearing damage is avoided;
(4) according to different performance requirements, different shear wall strengths and rigidities can be obtained by changing the section parameters of the corrugated steel plates on the two sides, the slit widths of the internally-arranged vertical slit steel plates, the arrangement forms and the like, so that different yield loads and corresponding yield displacements thereof are realized, and the design of controllable parameters is realized;
(5) the two sides are connected, so that the arrangement of openings such as doors and windows in the module unit is facilitated, and meanwhile, the steel plate shear walls connected on the two sides cannot bring transverse loads to the frame column, so that the overall stability of the structure cannot be influenced.
