Fantastic news! We've Found the answer you've been seeking!
Question:
Select a steel Beam using the “W” section from the AISC Manual for flexural members to support a service dead load of 1.0 k/ft (not including beam self-weight) & service lives load of 1.6 k/ft over the simply supported span of 18 ft. The beam section is made of A992 steel (fy=50 ksi). Also, calculate un-braced length “LP”.
