Challenge Problems
Push your limits with challenges.
Question 1
A building designed with a center of mass significantly offset from its center of stiffness is hit by a lateral seismic force. Calculate the resultant torsional effect considering the displacement patterns.
💡 Hint: Use calculations from torsional dynamics.
Question 2
In a seismic analysis of a 10-story irregular building, each floor has an unequal mass distribution. Model the building in a dynamic response simulation and assess if it meets seismic codes.
💡 Hint: Refer to simulation software for modeling structures under dynamic loads.
