TH $10$: Beams $-$ Basic, A$992$ Gr $50$

For an A$992$ W $3090$ beam, subjected to the following loads:

$K_{x_{p}in}=1\mathrm{.}0,K_{y_{p}in}=1\mathrm{.}0$

$P_{\text{D}\text{e}\text{a}\text{d}}=10(kips),P_{\text{L}\text{i}\text{v}\text{e}}=30(kips)$

$P_{\text{S}\text{n}\text{o}\text{w}}=0,P_{\text{R}\text{a}\text{i}\text{n}}=0,P_{Liv{e}_r\text{o}\text{o}\text{f}}=0$

$P_{\text{W}\text{i}\text{n}\text{d}}=0,P_{Ev}=0,P_{Eh}=0$
