Advanced Structural Analysis
Cass Hayward undertakes advanced structural analysis regularly and enjoys a special reputation for conducting complex engineering studies.
For example, we have been engaged at the forefront of improved techniques for investigating the effects of track-structure interaction and the dynamic performance of railway underline bridges. These methods were developed initially as part of our design commission for the reconstruction of the long-span crossing of Newark Dyke on the East Coast Main Line. This was the first major structure in the UK to be designed to accommodate high speed trains and the analytical work was focussed on ballast stability and passenger comfort working closely with the engineering standards group at Network Rail. The work developed thereafter to study the track-structure interaction effects of continuously welded rails on long railway structures and was used by us in practice first for the design of the reconstruction of the Leven Crossing of Morecambe Bay in Cumbria. The methods have now been adopted widely and adapted for inclusion in Eurocodes.
Other capabilities include the dynamic analysis of moving pedestrians, non linear and eigenvalue buckling analysis, wind induced aerodynamics, stress distribution for both static and fatigue analysis and dynamic effects of high speed trains.
