Water Flow Forces on Bridges - Convention …
Water Flow Forces on Bridges by Bennett & Ponnampalam Page 1 of 8 Water Flow Forces on Bridges Mark Bennett, Senior bridge Engineer (New Design) RTA Kumar Ponnampalam, Senior bridge Engineer (Technology and Practice), RTA Synopsis The 1992 Austroads bridge Design Code introduced the requirement to consider Water flow force effects acting on Bridges for floods up to the 1 in 2000 year average recurrence interval (ARI). Prior to that time it was common practice to design Bridges for flood events up to the 1 in 100 year ARI. With the requirement to consider flood events up to the 1 in 2000 year ARI, the superstructures of many Bridges are partially or completely submerged and a large range of superstructure types are subject to submergence. AS 5100 introduced new provisions for the calculation of Water flow Forces on Bridges , with significantly increased Water flow effects on bridge superstructures and increased debris loadings.
