2 cards from this section. Quick, good the night before a test.
What unique structural aspects make towers and chimneys susceptible to seismic forces?
Think about how gravity and motion affect tall structures.
Define overturning moments.
What happens to a tall structure when pushed?
What primarily causes higher mode effects in towers and chimneys?
Think about how height affects oscillation frequencies.
True or False: Overturning moments are not a concern in the design of tall chimneys.
Consider the forces acting on a chimney during a quake.
Analyze a scenario where a newly built chimney faces criticisms for its design in seismic-prone areas. What engineering measures would you recommend to improve its safety?
Consider energy dissipation techniques to reduce overturning forces.
Given a scenario where two towers of different heights experience the same seismic event, explain why the taller tower might suffer more damage, citing specific dynamics.
Think about the relationship between height and seismic response.
