The 15 m to 45 m (50 ft to 148 ft) span range is representative of the majority of bridges encountered in motorway, principal and trunk road schemes. The difference between an expensive and an economical bridge originates from a few very simple decisions at the design stage. The purpose of the paper, therefore, is to offer a few suggestions at a practical level the adoption of which should generally lead to economic solutions for the more regular bridge situations. M.V.

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.
