Challenge Problems
Push your limits with advanced challenges
An earthquake causes the ground to move up and down by 4 inches. If a structure moves in a way so that its relative displacement during the same time is 1 inch up, what is its absolute displacement?
💡 Hint: Add the ground displacement to the relative displacement.
Describe the effects of neglecting base motion in structural modeling during an earthquake. What potential risks could this introduce?
💡 Hint: Consider the implications of ignoring external forces acting on buildings.
