  • High-Strength Reinforcing Bars Technical Note

    4 High-Strength Reinforcing Bars ETN M-8-16 The slope of the initial lin-ear segment of the stress-strain curve is the modulus of elasticity Es. Note that test values of Es may be of the order of 26 000 000 to 28 000 000 psi because the bar area is not constant due to transverse deformations. However for design pur-poses Es is permitted to be

    The cross-sectional area is useful in determining a conductor s current-carrying capacity and resistivity. Rather than using fractional inches gauges are based on whole numbers with 38 commonly known sizes (4/0 to 36 AWG). Sizes smaller than 36 AWG can be calculated in gauge but wires larger than 4/0 are commonly expressed in 1 000 circular
