Abstract:ACI Committee 350 had two main objectives in revising its structural design recommendations. The first was to take advantage of the higher strength offered by the now standard Grade 60 reinforcing bars to reduce steel for economy. The second was to convert to the preferred strength design method. The developed revisions accomplished both objectives without imposing two-stage design procedures: one for structural safety and one for crack control to assure durability. Second-stage crack control is achieved by indirect means within the framework of the structural design procedure. The two principal new developments in materials affecting structural design, shrinkage-compensating cement and epoxy-coated bars, are recognized, but it was considered premature to attempt to prescribe specific variations in the complete design procedure permitted or required with their use .
