Variation of Supplemental Stiffness and Damping Using Adjustable Passive Fluid Spring and Damper in Scissor Jack System

Publication: Structures Congress 2009: Don't Mess with Structural Engineers: Expanding Our Role

Abstract

In this paper a new adjustable passive fluid spring and damper (APSD) is studied experimentally. The APSD is capable of varying the stiffness and damping independently; thus, the device can be used as an adjustable damper or as an adjustable fluid spring or as a combined stiffness and damping device. This allows a range of possibilities to modify structural stiffness and damping properties by placing the APSD at appropriate locations in the bracing system of the structure. In this paper the experimental results of the APSD under cyclic and ramp loading are presented. The versatile properties of the APSD are shown by means of experimental for displacement loops.
