Analysis of a Three-Span Continuous Grillage Having Varying Section Properties

Simply-supported bridge-decks are frequently designed as grillages so that the interaction between longitudinal main members can assist the load distribution when the deck has to carry the abnormal heavy vehicle (the H.B. loading of B.S.153). The analysis of simply-supported single-span grillages is now well established by the use of the ‘ quasi ’ slab technique. In recent years the number of continuous or otherwise statically-indeterminate bridge decksparticularly in prestressed concrete-has been increasing and where continuous decks have been adopted they have often been constructed with beams of varying depth and section properties. A demand has, therefore, arisen for an analytical technique for such continuous grillages. A. Goldstein, E. Lightfoot and F. Sawko
