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.

Question

6.8-4
A member in a braced frame supports an axial compressive load and end
moments that cause bending about both axes of the member. A second-
order analysis was performed with factored loads and reduced member
stiffnesses to obtain the moments and axial force. Use LRFD and select
the lightest W shape of A992 steel.
