$W_{DL}=$ self$-$weight only

$P_L=50k$

Beam is braced at ends only

See AISC Manual Table $3-1,$ p$3-18$ for values of $C_b$

LRFD Design Method:

a$.(5$ points$)$ Determine the moment that the beam needs to be designed to take assuming that the beamweight is approximately $0\mathrm{.}10\frac{k}{f}t.($HINT: See Table $3-22$ in the AISC Manual$)$

b$.(10$ points$)$ Select the lightest wide flange section that will support the loads shown.

ASD Design Method:

a$.(5$ points$)$ Determine the moment that the beam needs to be designed to take assuming that the beam selfweight is approximately $0\mathrm{.}10\frac{k}{f}t.$

b$.(10$ points$)$ Select the lightest wide flange section that will support the loads shown.

Deflection: $(5$ points$)$ For the beam selected by the ASD method, calculate the deflection at mid span due to Live Load ONLY: $($Use value of $C_1$ from Manual, page $3-9)$
