Seismic performance assessment of double corrugated steel shear walls with diagonal waves

In this paper, the seismic performance of trapezoidal and sinusoidal corrugated steel plate shear walls has been investigated in comparison with the flat steel plate shear walls in conditions where the amount of steel materials used in the shear walls does not change and remains constant. First of all, the sinusoidal or trapezoidal shear walls are created with a specific and predefined geometry, and then the created wave is placed diagonally in the form of two steel plate shear walls with double perpendicular waves in the steel frame, in other words, the geometry of the flat steel plate shear walls changes to achieve optimal seismic performance. The studied steel plate shear walls in this research were compared using uniform nonlinear static analysis and obtaining their pushover diagram as well as hysteresis analysis and obtaining the hysteresis cycle and plastic energy absorption by finite element method. Finally, it was concluded from studied frames that trapezoidal and sinusoidal corrugated steel plate shear walls in the form of two shear walls with double perpendicular waves produce better seismic performance and energy absorbing than flat steel plate shear walls with the same volume of steel materials and trapezoidal steel plate shear walls produce better seismic performance comparing to the sinusoidal corrugated steel plate shear wall.
