Case Study 1: Three Span Bridge
A preliminary assessment was carried out on this UK highway bridge using ring2.0.
In advance of performing an intrusive investigation, a variety of scenarios were explored, including the case where masonry backing material was present above the piers (commonly encountered in multi-span bridges).
In this case the critical failure mechanism involved two spans - clearly demonstrating that it is potentially unsafe to analyse the bridges as a series of single spans simply because the piers are deemed by some measure to be 'stocky' (as advocated in certain assessment codes).
