Shock Transmission Unit (STU)

The Well-Link Shock Transmission Unit (STU) is a temporary connection device (TCD), velocity dependent, which allows the displacement of elements of a structure in service, but rigidly connect them under shock loads caused by earthquakes or other events. Well-Link STU consists of a cylinder, a piston road and a piston through which an internal fluid flows. Unlike Fluid Viscous Damper (FVD), STU does not absorb or dissipate energy, and it is also known as lock-up device, displacement-control device or snubber, among others.
