Reinforced Concrete Design
ARCH 331 Note Set Su2014abn Reinforced Concrete Design Notation: a = depth of the effective compression Es = modulus of elasticity of steel block in a Concrete beam f = symbol for stress A = name for area fc = compressive stress Ag = gross area, equal to the total area fc = Concrete Design compressive stress ignoring any reinforcement fpu = tensile strength of the prestressing As = area of steel reinforcement in reinforcement Concrete beam Design fs = stress in the steel reinforcement for As = area of steel compression Concrete Design reinforcement in Concrete beam fs = compressive stress in the Design compression reinforcement for Ast = area of steel reinforcement in Concrete beam Design Concrete column Design fy = yield stress or strength Av = area of Concrete shear stirrup F = shorthand for fluid load reinforcement Fy = yield strength ACI =
to penetrate to the steel, a corrosion cell will be created, the steel will rust, expand and cause further cracking. Adequate cover of the steel by the concrete is important. Deformed reinforcing bars come in grades 40, 60 & 75 (for 40 ksi, 60 ksi and 75 ksi yield strengths). Sizes are given as # of 1/8” up to #8 bars.
