Challenge Problems

Push your limits with challenges.

Question 1

Calculate the reliability index for a structural member given its load-carrying capacity and the expected load. If the load-carrying capacity is 9,000 lbs and expected loads vary but average at 8,500 lbs, can you assume it’s sufficient based on P = 1 - social concern?

💡 Hint: Think about how normal distribution defines safety in margins.

Question 2

Discuss what changes would need to occur if a structure was found to have a low reliability index after completion. What steps should an engineer take?

💡 Hint: Consider all alternatives engineers utilize to enhance structural integrity.
