Situation:

A W$14$x$90($Fy$=345$ MPa$)$ is simply supported beam with a span length of $45$ feet. It is laterally supported at its

ends only. Determine the flexural strength of the member. Use LRFD and ASD. $($Use the Metric Table for the properties of the section.$)$ Cb$=1\mathrm{.}14$

Guide:

$-$ Determine whether the shape is compact, noncompact, or slender using Table B$4\mathrm{.}1$b$.$

$-$ Based on its classification, refer to Table User Note F$1\mathrm{.}1$ for the applicable section from sections F$2-$F$13.$

$-$ Solve the design and allowable flexural strengths.
