000009845 520__ $$2eng$$aTo mitigate base displacement in structural seismic isolation for large input level earthquake while performing well for moderate input level earthquakes, variable oil damper (VOD) has been proposed and small-scaled model has been developed. The basic idea of this VOD consists of enhancing damper force by tunable internal mechanism (without computer or power supply) when base displacement overreaches limit value (set length). Using the seismic simulator to provide the input motion, the mechanical properties of the VOD model were identified. Experimental studies showed that damper force increased as base displacement exceeds damper’s set length. Numerical model of VOD is employed to investigate effect of the VOD parameters on behavior of a real eight story building in different input ground motions. Results of analytical study demonstrated effectiveness of VOD to decrease base displacement while maximum acceleration, shear and interstory displacement of superstructure are slightly increased.
