Abstract

The ability to effectively manage the deterioration of a network-wide bridge stock condition from year to year is vital for the effective use of finite resources while maintaining public safety. The leading cause of bridge failures and deterioration globally is bed scour. This paper looks at the development of a novel Fibre Bragg Grating (FBG) Vortex Flow Sensor (VFS) for scour utilising vortex-induced vibration flow effects. These sensors can provide early warnings to bridge managers and allow for a proactive approach to scour management at vulnerable bridges. This paper briefly reviews the current types of scour sensors available before outlining the initial development of the novel VFS setup and associated prototype development. The initial findings of lab trials are presented before outlining the selection process for a masonry arch bridge test site.
