Three-Hinge Analysis of Masonry Arches

Brief reviews of the behaviour of masonry arch bridges and of popular methods of analysis highlight the need for a simple, practical analysis of arches under working loads. A three-hinge model is proposed and is shown to lead to the same solution as four-hinge mechanism analyses when the structure approaches ultimate load. The three-hinge method is extended to enable failures by local crushing of the masonry to be simulated. It is also shown to permit realistic allowances to be made for movements of abutments. F.W. Smith, W.J. Harvey and Professor A.E. Vardy
