Shear Behavior of Squat Steel Fiber Reinforced Concrete (SFRC) Shear Walls with Vertical Slits

摘要

Three 1/3-scale squat steel fiber reinforced concrete (SFRC) shear walls with height-to-length ratio of 0.55 were manufactured and tested up to failure. Two walls (SFRC-SS and-LS) are similar to each other except the height (230 and 460mm) of vertical slits with the width of 40mm. For comparison, solid wall (SFRC-NS) was made. All specimens had the same rectangular cross-section of 1,100mm x 50mm, with wall panel height of 600mm. The experimental results showed that squat SFRC shear walls with vertical slits exhibited more stable hysteretic behavior than a solid SFRC shear wall. Vertical slits on the squat SFRC shear walls improve the ductility and energy dissipation capacity but decrease the load-carrying capacity and stiffness of squat SFRC walls.
