WebAnother type of friction damper is Pall friction damper. (figure 1-2-1-2). This damper includes a bracing and some steel plate with friction screws. And they should be installed in the middle of bracing. Steel sheets are connected to each other by high strength bolts and they have a slip by a certain force, to each other. http://palldynamics.com/FrictionDampers.htm WebOct 1, 2024 · Friction damper Friction dampers generally are constructed by clamping steel plates together. The friction mechanism between the plates dissipates input energy. These dampers are designed for an optimum slip load so that the main members do not yield before dampers slip. caja bonobon
