Cyclic and Push-over ductile behavior of steel shear wall strengthened with stiffeners and steel column filled with concrete
Based on the several advantages of steel shear walls as lateral resistant system (stiffness, strength, ductility and energy absorption), the cyclic and nonlinear analysis of steel shear walls strengthened with vertical and horizontal stiffeners and boundary columns filled with concrete was investiga...

Based on the several advantages of steel shear walls as lateral resistant system (stiffness, strength, ductility and energy absorption), the cyclic and nonlinear analysis of steel shear walls strengthened with vertical and horizontal stiffeners and boundary columns filled with concrete was investigated in this paper and displacement controlled analysis at ABAQUS F.E. based on ATC24 protocol for different models were conducted. The numerical model was calibrated with experimental results and then four new steel shear wall models with vertical and horizontal stiffeners and steel column filled with concrete were considered and analysed. The hysteresis curves results conducted in this paper indicated that the steel shear wall with stiffeners and boundary column filled with concrete strength was higher than post-buckling strength, and the steel plate post-buckling strength was fully gained due to increasing rigidity of boundary columns. The absorption energy of strengthened specimen filled with concrete in push-over analysis was 11% higher than non-strengthened specimen without concrete, and also the total energy absorption at cyclic loading of strengthened specimen was 415% (5.15 time) comparing to non- strengthened specimen indicating that this combined stiffeners and concrete filled column was effective. The behaviour ratio of strengthened specimen was 21% more than that of non-strengthened specimen. |
