Improved Strength Design of Reinforced Concrete Hydraulic Structures - Research Support

Abstract

Strength design (SD) criteria for reinforced concrete hydraulic structures (RCHS) have been based on a procedure that resulted in equivalence with the working stress method given in Engineer Manual 1110-1-2101, dated 1963. Recent studies have been directed toward reducing the conservatism associated with the working-stress-equivalent SD procedure, thereby, improving the economy of RCHS. Parametric studies indicate that an adjustment to the ACI 318-89 load factors results in close agreement with working stress designs for tension- control failures and for pure compression failures. These are the failure zones that are of primary interest for the design of RCHS. Also, serviceability is a primary concern for RCHS. In regard to serviceability, a primary parameter considered in this study was the ratio rho max (steel ratio as a fraction of the balanced reinforcement ratio).
