Challenge Problems

Push your limits with challenges.

Question 1

Given a structure with a known base shear capacity of 200 kN and a observed top displacement of 10 cm, calculate the new base shear capacity if the stiffness degrades leading to a 30% reduction in capacity.

💡 Hint: Consider how reducing stiffness affects overall capacity.

Question 2

Analyze a scenario where retrofitting a building adds shear walls, improving its capacity measured by a performance point increase from 300 kN to 400 kN. Discuss implications for seismic design.

💡 Hint: Referring back to how performance points interact with design principles will help.
