A flitch beam can be fabricated by sandwiching two steel plates (2) between three wood boards (1). Dimensions for the cross section are b- 1.2 in., d= 7.3 in., and t-0.30 in. The elastic moduli of the wood and steel are E - 1700 ksi and E2 -31500 ksi, respectively. For a bending moment of M, - +13.5 kip-ft, determine: (a) the normal stress in each material at point H, which is located at a distance of a - 1.8 in. above the z centroidal axis. (b) the normal strain in each material at point H. (c) the magnitudes of the maximum bending stress in each material. (2) d (1) (1) (1) b Answer: (a) Owood(H) - i psi Osteel(H) = i psi (b) Ewood(H) " HE Esteel(H) - (c) Owood(max)- psi Osteel(max)- psi

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.
