Challenge Problems

Push your limits with challenges.

Question 1

A 10-story building experiences a lateral drift of 0.1 m due to an earthquake. If the axial load at the base is 500 kN, calculate the increased moment due to the P-Delta effect at a height of 30 m. Assume the lever arm is equal to the height of the building.

💡 Hint: Remember the formula for moment: Moment = Force x Distance.

Question 2

Propose a modification to improve the seismic resistance of a tall building experiencing significant P-Delta effects. Detail your approach and the expected outcomes.

💡 Hint: Think about foundational strategies that can mitigate lateral movement.
