Abstract:
Examples of detailing practices related to design and construction of reinforced concrete structural walls are discussed. Areas covered are transverse reinforcement in vertical boundary elements and an-chorage of horizontal wall reinforcement within hinging regions of structural walls. Functions of transverse reinforcement are illustrated using results from laboratory tests of structural Walls. The four primary func tions discussed are increase in limiting strain capacity of concrete, sup port of vertical reinforcement against inelastic buck. ling, containment of concrete, and improvement of shear capacity and stiffness. Recommendations for details of hoop and supplementary crossite reinforcement are made. Details for proper anchorage of horizontal wall shear reinforcement are suggested
