Abstract

The concept of a semiactive hydraulic vibration absorbers (SAVA) for bridges is introduced. The paper demonstrates that by retrofitting a bridge with this control system, vibrations that are caused by large trucks can be reduced by over 50 percent. SAVA are particularly suited to installation on bridges in remote areas, because the system requires no electrical line power or hydraulic pump. Trade off studies were made to determine appropriate actuator size and layout. The new system can add tens of years of life to a bridge. Alternatively, the new system will make it possible to increase maximum allowable truck weights without reducing the expected service life of the bridge.
