Abstract:
This paper summarizes the results of an experimental and analytical study of slender reinforced concrete structural walls with an opening at the base. The primary objectives of this research were the evaluation of a displacement-based approach for the selection of transverse boundary reinforcement, and the evaluation of a strut and tie model for the selection of the horizontal shear reinforcement. Two approximately quarter-scale wall specimens were constructed and tested under constant axial stress and reverse cyclic lateral loading. Experimental results show that, when designed using a combined displacement-based and strut and tie approach, slender structural walls with openings at the base exhibit stable hysteretic behavior and significant ductility. The displacement-based design technique allowed transverse boundary reinforcement to be provided as needed rather than selected based on a nominal value. The strut and tie model was found to be an effective tool for the design of discontinuous regions, where simplified code equations are not appropriate.
