Description
Technical Field
The utility model relates to a structure of compriseing dysmorphism cross-section post frame and wave form steel sheet wall belongs to structural engineering technical field.
Background
Frame-shear wall structures are widely used in residential construction as a side force resistance. The frame-shear wall structure consists of a frame and a shear wall. Compared with the traditional reinforced concrete frame and the traditional shear wall, the steel frame and the steel plate shear wall are convenient to construct, and the bearing and deformation performance of the structure under the action of horizontal reciprocating loads such as earthquake and the like can be improved through reasonable design, so that the structure obtains superior energy dissipation and shock absorption characteristics. In a building structure, a steel frame mainly bears axial force and bending moment, and a steel plate shear wall mainly bears horizontal force. The steel plate shear wall generally keeps elasticity under the action of wind load or small earthquake, plays a monotonous bearing role, can enter plasticity under the action of large earthquake, dissipates earthquake input energy through reciprocating hysteresis, and plays dual roles of bearing a component and dissipating energy and damping. However, in actual use, the frame brings the problem of exposed beams and exposed columns, the stress performance and the normal use function of the common flat steel plate shear wall are limited, the problems destroy the architectural appearance, limit the architectural area and influence the application of the steel frame-steel plate shear wall.
When the frame-shear wall structure is applied to a residential structure, the thickness of the frame columns tends to be inconsistent with the wall. Reinforced concrete frame generally adopts the rectangle cross section post, and steel framework generally adopts H shape steel or rectangle steel pipe frame post, all is leading to the frame post to bulge, and the beam column node exposes in the indoor space simultaneously. The section form of the frame column is changed to be consistent with the thickness of the wall body, so that the frame column is matched with the structural plane arrangement, and the problem of exposed beams and exposed columns can be solved.
When the steel plate shear wall takes a flat steel plate as the embedded steel plate, the steel plate shear walls with different height-thickness ratios have different working mechanisms. The thick steel plate shear wall with the small height-thickness ratio generally does not buckle before yielding, and the full-section yielding of the steel plate is taken as the bearing capacity limit state, so that the thick steel plate shear wall is large in steel consumption and high in construction cost. The steel sheet shear wall with the large height-thickness ratio can be buckled before yielding, the buckled steel sheet forms an oblique tension belt, stable bearing performance after buckling is achieved, and the steel consumption can be saved. However, the steel sheet tension band puts higher requirements on the strength and rigidity of the edge beam column, the pinch-in phenomenon of the hysteretic curve of the steel sheet shear wall under the action of reciprocating load occurs, and meanwhile, the steel sheet repeatedly bends to generate huge noise to influence the normal use of a building structure.
When the corrugated steel plate is used as the embedded steel plate, the out-of-plane rigidity of the steel plate shear wall is obviously increased, the buckling load under the action of in-plane shear force is obviously improved, and the buckling can be prevented from occurring before yielding by using a small steel consumption. The bearing performance of the corrugated steel plate shear wall is superior to that of a thin steel plate shear wall with the same steel consumption, and the corrugated steel plate shear wall shows a working mechanism similar to that of a thick steel plate shear wall. Meanwhile, the corrugated steel plate is not easy to deform under the action of external force, and the transportation, construction and installation of components are facilitated. Corrugated steel sheets are formed by cold rolling flat steel sheets, and the thickness of the corrugated steel sheet is limited by the ductility of the steel and the capability of processing equipment, and generally does not exceed 8 mm. The bearing performance of the corrugated steel plate shear wall is limited, and the application of the corrugated steel plate shear wall in a high-rise building structure with a horizontal load control function is hindered.
In order to solve the limitation that frame-shear wall structure exists in practical application, the utility model provides a dysmorphism cross section post frame-wave form steel sheet wall structure adopts the dysmorphism cross section post to improve the frame, adopts single wave form steel sheet wall, the wave form steel sheet wall of putting more energy into, the double wave form steel sheet wall that parallel butt joint connects and the double wave form steel sheet wall that the quadrature butt joint connects etc. to improve the steel sheet shear force wall, has great economic benefits in residential housing structural application.
