Control of the Dynamic Response of Classical Columns with Defects
Abstract
This paper investigates the protection of classical columns in areas of seismic activity using passive control techniques. Small scale multi-drum column-models with a damaged bottom drum or inclined base are considered under random excitation. Their response without any protection is measured and compared with their response when an impact damper is attached to them. The damper takes the form of a drum that looks exactly like the rest of the drums but is hollow and contains particles. It is found that the damper, if it is properly designed, can reduce effectively the motion of classical columns (reaching levels up to 40%) without altering their overall appearance.
