Concept explainers

Bars

In civil engineering, bars refer to steel reinforcement bars or rebars. These are structural members primarily used for reinforcement purposes in masonry works. A bar is characterized by its cross-sectional area, which is negligible compared to its length. Bars are usually manufactured by steel which is uniform throughout the length, or by meshing multiple steel wires. Other materials of the bar include carbon steel, glass fiber, carbon fiber, and basalt fiber. The reinforcing bars are coated with epoxy resins and other materials to enhance some of their properties including corrosion resistance.

A pretensioned prestressed beam has a rectangular cross section of 6 in. width and 20 in. total depth. It is built using normal-density concrete with a specified strength f = 4000 psi and a strength at transfer of f' = 3000 psi. Stress limits are as follows: fi = 164 psi, f. = -1800 psi, f. = 474 psi, and fes = -1800 psi. The effectiveness ratio R may be assumed equal to 0.80. For these conditions, find the initial prestress force P, and eccentricity e to maximize the superimposed load moment My + M, that can be carried without exceeding the stress limits.
