A simply supported beam with a span length of 48 feet is laterally supported at its ends and is subjected to the following service loads: Dead load = 400 lb/ft (including the weight of the beam) Live load = 1000 lb/ft If Fy = 50 ksi, is a W14 x 99 adequate? a) Check the capacity based on the limit state of flange local buckling (2) b) Check the capacity based on the limit state of lateral-torsional buckling (Lb) A simply supported beam with a span length of 48 feet is laterally supported at its ends and is subjected to the following service loads: Dead load = 400 lb/ft (including the weight of the beam) Live load = 1000 lb/ft If Fy = 50 ksi, is a W14 x 99 adequate? a) Check the capacity based on the limit state of flange local buckling (2) b) Check the capacity based on the limit state of lateral-torsional buckling (Lb)

Answer rating: 100% (QA)

SOLUTION a To check the capacity of the W14x99 beam based on the limit state of flange local buckling we need to calculate the bending stress due to the service loads and compare it to the allowable b... View the full answer
