Challenge Problems
Push your limits with advanced challenges
A building designed with steel beams faces extreme seismic loading. Discuss how the design should consider both material and geometric nonlinearity and the methods to analyze these effects.
💡 Hint: Consider both types of nonlinearity and tools like FEA.
Evaluate a structure that experienced unexpected damage during an earthquake despite being designed per code standards. Analyze the potential impact of neglecting nonlinearity in both design and analysis.
💡 Hint: Look at the limitations of conventional linear analysis in dynamic events.
