Dampers: shock absorbers for buildings

Earthquake engineer Nicos Makris joins us to discuss protective dampers, large-scale devices that function like shock absorbers for buildings and bridges. Dampers built into a structure absorb and isolate earthquake, wind, and traffic vibrations. Prof Makris reveals a new type of damper he’s designed that uses pressurized sand to address hydraulic failures in oil-based dampers.
