The Effect of Infill Steel Plate Thickness on the Cycle Behavior of Steel Plate Shear Walls

What is it about?

Steel plate shear wall (SPSW) is commonly used in civil schemes because of its good deformability and stiffness. In this research, the numerical analysis of steel plate shear wall (SPSW) with unstiffened infill steel plate is conducted. This paper explains the effect of thickness variation of infill steel plate on behavior of steel plate. In this status, several samples are designed and checked by rigid frame and actuator. The experimental samples is joined to a rigid frame. 3 numerical specimens consist of steel plate shear wall with different thickness (1.5, 3, 4. 5) mm formed by finite element code which is advanced by the Amirkabir university. To confirm the model, numerical results were discussed with a valid experiment which explain suitable agreement. Numerical model tested under cyclic loading with frequency of 1/60 Hz. Results show that the increase of infill steel plate thickness enhance stiffness and ductility ratio of model. And so, would decrease energy absorption in comparison with the reference model.

Why is it important?

The nonlinear program ANSYS 13.0 used to construct validity of analyzed model of steel shear wall specimen (1000*2000 mm) on which the thickness of infill steel plate is 3 mm, and height overall ratio to the span is 1/2. Applied under cyclic loading and its deformation-load diagram plotted and compared to the analyzed results of similar numerical model Figure 4. Table 1 show the compering result between experimental and numerical analysis.
