Re: Neoprene Bearing Pads - Coefficient of Friction

[Subject Prev][Subject Next][Thread Prev][Thread Next]
                The coefficient of friction between Neoprene and steel is higher than the shear deformation capacity of a properly designed bearing pad.
                Three Nelson studs will not secure the bearing plate in a double tee stem _if the bearing locks up_; a tail bar would required. ACI discusses this for corbels, Section and the Commentary thereof. Due to equal and opposite reactions, the same force will develop in the tee stem. However, an adequate bearing pad relieves the forces by shear deformation.
