Challenge Problems
Push your limits with challenges.
Question 1
A building is designed to withstand a maximum live load of 1000 kg. During an unexpected event, it faces a load of 1500 kg. Assess the potential consequences, ensuring to include discussions on safety factors.
💡 Hint: Consider how much the safety factor amplifies the design loads.
Question 2
Discuss and calculate the necessary load factor for a bridge that must support a maximum expected live load and an additional safety margin. Assume design specifications allow for a safety margin of 1.5 for unexpected conditions.
💡 Hint: Link the calculations back to the purpose of safety provisions to justify the results.
