Embodiment 1

[0026] Such as image 3 As shown, a steel plate shear wall includes a peripheral column 1, a peripheral beam 2 and an inner filling plate 3. The peripheral column 1 and the surrounding beam 2 are cast and formed by a pre-concrete pouring process. The function of the inner filling plate 3 is to increase the wall The shear resistance of the body can effectively increase the strength of the shear wall. There are slits 31 on the inner filling plate 3, which can effectively convert the shear force borne by the wall into the bending stress of the inner filling plate 3, thereby effectively absorbing energy and preventing the wall from being damaged. The slit 31 is arranged horizontally, and extends from the contact position between the inner filling plate 3 and the peripheral column 1 to the inside of the inner filling plate 3. Through this arrangement, the inner filling plate 3 is divided into several leaf springs, and the horizontal setting of the spring can effectively absorb the ...

Abstract

The invention discloses a steel plate shear wall, which comprises a peripheral column, a peripheral beam and an inner filling plate. Not intersecting, extending from the contact point between the inner fill plate and the surrounding columns to the inside of the inner fill plate, the inner fill plate is connected to the surrounding columns, and the inner fill plate is not connected to the surrounding beams. Compared with the prior art, the present invention has the following advantages: by adjusting the spacing and length of the slits, the rigidity of a single wall body can be changed conveniently. The steel plate is only connected to the surrounding columns, and no additional bending moment is generated on the columns, which conforms to the seismic concept of strong columns and weak beams, and has good plasticity and hysteresis performance. By setting vertical and transverse ribs, the mechanical performance and ductility of the shear wall are improved, the elastic stiffness of the inner fill plate is improved, and it has a stable and full hysteresis curve in the elastic-plastic range, which overcomes the hysteresis of the thin steel plate. The "pinch" phenomenon of the back curve.

Description

technical field [0001] The invention relates to the construction field, in particular to a steel plate shear wall. Background technique [0002] The steel plate shear wall refers to a structure in which steel plates are filled between some frame beams and columns on the basis of a steel frame structure in order to improve structural rigidity and seismic performance. Research scholars generally believe that this is a structural form with good seismic performance. This structure is light in weight, fast in construction, and has withstood the test of earthquakes. [0003] In recent years, the steel plate shear wall structure that has begun to emerge in North America and Japan is generally considered by researchers to be a structural form with good seismic performance. The steel plate shear wall structure refers to a structure in which steel plates are filled between some frame beams and columns on the basis of a steel frame structure in order to improve structural rigidity an...
