Challenge Problems
Push your limits with challenges.
Question 1
A structural member has a theoretical strength of 12000 lbs with a resistance factor of 0.85. If the total service load on this member is 9000 lbs, will it safely support the load based on LRFD?
💡 Hint: Calculate factored strength and verify it against the load.
Question 2
Design a beam using LRFD principles that requires supporting a factored load of 15000 lbs. If the member's resistance factor is 0.75, what must be the minimum theoretical strength to ensure safety?
💡 Hint: What formula do you apply to determine required strength for design?
