Webeffect of friction damping versus that same building without such damping. It then corroborates these findings by presenting the results of physical experimentation on a scale model of the building, both with and without damping. The validation of the virtual models by the physical model provides credence to the usage of friction-damped braced http://palldynamics.com/FrictionDampers.htm
