PENDULUM TYPE LIQUID COLUMN DAMPER (PLCD) FOR CONTROLLING THE VIBRATION OF A BUILDING STRUCTURE

摘要

The present invention provides a passive damping device (14) comprising an U- tube type like container (1) with to upwardly pointing arms (6) and one horizontal arm (5), partly filled with liquid and fixed to a holding structure (2) which is hingedly attached to a building structure (16), so that it can move like a pendulum relative to the building structure (16). The source of damping in this device is due to the sloshing motion of the liquid in the U-tube container (1) as it passes through an orifice (4) arranged within the bottom of the horizontal arm. (5)
