The Distribution of the Clamping Pressure in Friction-grip Bolted Joints

A brief description is given of the finite-element method used to obtain the distribution of clamping pressure at the interfaces of lap joints. Relations are presented which enable the pressure to be calculated for ranges of the geometrical parameters likely to be found in structural steelwork joints, and the significance of the results obtained is discussed in relation to the strength of steels and the grades of bolts in common use.
