Side And Seismic Performance Of Sinusoidal Opening Corrugated Steel Plate Shear Wall The Study

As a new type of lateral force resistant member,corrugated steel plate shear wall has gradually become the focus of engineering and academic circles because of its advantages such as large out-of-plane stiffness,convenient installation and saving construction period,but it is mostly used in non-seismic areas.The research on its seismic performance and lateral resistance is not enough.Therefore,in this paper,the lateral stiffness of sinusoidal corrugated steel plate and the lateral and seismic performance of sinusoidal corrugated steel plate shear wall are studied by using the finite element software ABAQUS.The main contents are as follows:First of all,the effects of the geometric parameters of sinusoidal perforated corrugated steel plate on its lateral stiffness are analyzed in different plate length,plate height,plate thickness,corrugated plate wave crest height,hole height,hole length and hole position geometric parameters.The results show that with the increase of the length of the corrugated plate,the height reduction,the height of the wave peak decreases,the thickness increases,the length of the hole narrows and the height of the opening reduction,the lateral stiffness of the sinusoidal corrugated steel plate increases,but its growth rate decreases continuously.The influence of the length of corrugated steel plate and hole length on the lateral stiffness is more obvious.Secondly,the effects of different plate length,plate height,plate thickness,corrugated plate peak height,hole width,hole position and hole shape geometric parameters on the buckling mode and lateral resistance of sinusoidal perforated corrugated steel plate shear wall are analyzed.The results show that the buckling of the corrugated steel plate shear wall generally occurs at the edge of the hole,and the length,height,peak height and thickness of the corrugated steel plate increase.The width and shape of the hole have a significant impact on the buckling mode and lateral resistance of the sinusoidal corrugated steel plate shear wall,while the height of the corrugated steel plate has little effect on the lateral resistance of the sinusoidal corrugated steel plate shear wall.Compared with the sinusoidal perforated corrugated steel plate shear wall,the initial lateral stiffness,buckling load and peak load of the sinusoidal perforated corrugated steel plate shear wall are reduced,but the out-of-plane stiffness of the sinusoidal corrugated steel plate shear wall is increased.Finally,the effects of sinusoidal perforated corrugated steel plate on the seismic performance of sinusoidal perforated corrugated steel plate shear wall are analyzed under different plate length,plate height,plate thickness,corrugated plate peak height,hole width,hole position and geometric parameters of hole shape.The results show that the increase of length,height,crest height,thickness,width and shape of corrugated steel plate all significantly affect the seismic performance of sinusoidal corrugated steel plate shear wall.Compared with the direction of flat steel plate shear wall with sinusoidal opening,the hysteretic curve of sinusoidal corrugated steel plate shear wall is fuller,the energy dissipation capacity is better,and the area of corrugated steel plate entering plasticity is larger.
