A simply supported beam is subjected to a uniform service dead load of 1.0 kips/ft (including the weight of the beam), a uniform service live load of 2.0 kips/ft, and a concentrated service dead load of 40 kips. The beam is 40 feet long, and the concentrated load is located 15 feet from the left end. The beam has continuous lateral support, and A572 Grade 50 steel is used. Is a W30 × 108 adequate? a. Use LRFD. b. Use ASD. Pp = 40 k 15'- 25'- Wp = 1.0 k/ft WL = 2.0 k/ft W30 X 108 40'-
