Why are Taylor Fluid Viscous Dampers better than friction dampers such as sliding joints and plastic hinges?
There are three major differences between our Fluid Viscous Dampers and friction devices. The primary difference is that the constant force output of a friction damper increases maximum column or pier stress under any deflection of the structure. Fluid Viscous Dampers do not increase column stresses due to their inherent out of phase response output. The second difference is that friction dampers put out an essentially constant force when deflected, independent of velocity. This response causes continual stress in the structure during all thermal expansion and contraction of the structure. Fluid Viscous Dampers put out virtually zero force at the low velocities associated with thermal motion. The third difference is that friction dampers restrict a structure from restoring itself to its original position after seismic events. Fluid Viscous Dampers allow the structure to re-center itself perfectly at all times. Q: How do Taylor Fluid Viscous Dampers compare to visco-elastic devices? A:
