Push your limits with advanced challenges
A structural engineer is designing a beam that will be subjected to a dead load of 50 lb/ft and a live load of 40 lb/ft. If the load factors for dead and live loads are 1.2 and 1.6 respectively, what is the factored load the beam needs to resist?
💡 Hint: Apply the load factors to each load type.
An architectural student needs to create a realistic load combination for a design that includes snow and wind influences. If the dead load is 30 lb/ft, the wind load factor is 1.5, and the snow load factor is 1.2, illustrate a reasonable load combination.
💡 Hint: Remember to weigh both the loads by their factors before combining.
