Splices are normally needed when access limitations make it very difficult to get a long steel beam where it needs to go. The design of the splice allows the beam to be delivered in 2 (or more) sections which are then simply bolted together when they are in position.

The splice consists of steel flange plates and web plates and the size of the plates and the number of bolts used is designed such that the connection can be as strong as the rest of the beam if required, or less than this if it is not. All steel beam splices should be properly designed so as not to compromise the strength of the beam.

Our structural calculations for a steel beam splice includes the design of all the necessary splice plates, welds and bolted joints.

We need the following information to design a steel beam splice:

the span of the beam

the section size of the beam (eg a 203x133x30UB)

if the beam supports a floor, details of the floor construction (timber or concrete)

the position of the splice along the beam

Design information

All design work is carried out in accordance with BS5950 (The structural use of steelwork).

The calculations provided will be suitable for Building Regulation approval.
