Consider a simply$-$supported beam with clear span Ln $=30$ ft$.$ The beam is subjected to an ultimate

factored load wu $=8$ k$/$ft $($includes self$-$weight$)$ and that the factored live load wuLL $=6$ k$/$ft$.$ Assume the

beam is $20$x$34($b x h$)$ with $4-$#$10$ bars on the top and bottom.

$($a$)$ Determine the shear envelope.

$($b$)$ Design appropriate shear reinforcement. Show on a figure.
