The design of large span corrugated steel structures

In this report the behaviour of flexible corrugated steel buried structures of spans ranging between 0.9 metres and 14 metres is investigated, with particular emphasis upon large span structures of 7 metres and above which incorporate thrust beams. The report includes a review of design methods, a finite element study of the behaviour of arch and ellipse large span structures, and a review of technical literature encompassing model testing, full scale load testing and finite element modelling (FEM). The basis for a practical design method for large span ellipse and arch structures incorporating thurst beams is given.
