Two-side-connection lateral-reinforcing and unequal-height vertical-gap forming steel plate shear wall

Abstract

The invention discloses a two-side-connection lateral-reinforcing and unequal-height vertical-gap forming steel plate shear wall which is composed of a steel board with gaps, an upper edge frame beam, a lower edge frame beam, an upper end steel angle and a lower end steel angle. The two-side-connection lateral-reinforcing and unequal-height vertical-gap forming steel plate shear wall is characterized in that the upper end of the steel board with the gaps is connected with the upper end steel angle, and the lower end of the steel board is connected with the lower end steel angle; the upper edge frame beam and the lower edge frame beam are respectively connected with the steel board with the gaps through the upper end steel angle and the lower end steel angle; the vertical gaps are distributed in the steel board with the gaps at equal distance, and the lengths of the vertical gaps gradually become small from the outer side to the center. The connecting lines between the upper ends of the vertical gaps and the lower ends of the vertical gaps are symmetrical broken lines or symmetrical arcs.

Description

technical field [0001] The invention belongs to the field of structural engineering, in particular to a steel plate shear wall with vertical seams connected at both sides. Background technique [0002] At the beginning of this century, Japanese scholar Toko Hitaka proposed the concept of steel plate shear wall with slots. By rationally opening vertical joints on the steel plate, the wall plate can work like a series of bending wall piers under lateral load, changing the traditional steel plate shear force. The stress state of the wall is dominated by in-plane shear deformation or post-buckling tension field, so that the wall panel is mainly subjected to bending deformation, thereby improving its deformation capacity and energy dissipation capacity. However, this method of opening vertical joints on the steel plate is at the cost of sacrificing the stiffness and ultimate bearing capacity of the shear wall. According to the data, it is more difficult for the wall panels with ...

Problems solved by technology

According to the data, it is more difficult for the wall panels with smaller height and width ratios to achieve pre-buckling yield for the steel plate shear walls with uniform slots.
