Behavior and strength of rib stiffened SC wall-slab connection was investigated. Six prototype specimens of wall-slab connections were fabricated and tested. Structural safety of the specimens was confirmed through the monotonic loading test.
Based on the experimental observations, strength formula of the joint was proposed. To enhance the reliability of the proposed strength formula, analytical verification was performed through inelastic finite element analysis. Effect of parameters, such as, load point, friction coefficient, on the joint strength was examined. Finally, it was confirmed that the proposed formula gives
conservative value in most cases.
