Tony Gee and Partners used LUSAS Bridge for the analytical study of load and stress distribution of Neasden Lane Overbridge in London. The bridge comprises two historically distinct deck systems that are proposed to be made composite by installing a load sharing mechanism. Re-assessment of the bridge superstructure to UK Bridge Assessment of a Composite Deck System code BD 21/01 for 40tonne loading was required as part of the Neasden Lane Overbridge Network Rail Framework Contract BG3 Programme. As a result of the assessment significant savings in time and costs were made over previous strengthening proposals.
