- Examples of detailing practices related to design and construction of reinforced concrete structural walls are discussed. Areas covered are confinement reinforcement in vertical boundary elements, and anchorage of horizontal wall reinforcement. The functions of confinement reinforcement are illustrated using results from laboratory tests of structural walls. The four primary functions discussed are the increase in limiting strain capacity of concrete, the support of vertical reinforcement against inelastic buckling, the containment of concrete, and the improvement of shear capacity and stiffness. Recommendations for details of hoop and supplementary cross-tie reinforcement are made. Details for proper anchorage of horizontal wall shear reinforcement are suggested. Several areas of needed research are outlined.
