The British army has a long history in the design and construction of military bridging, its latest bridges being made of large welded sections pinned together to form trackways. To utilise the strength of these bridges, there needs to be rapid assessment of the damage and then simple rules which can be applied to the assessment to indicate the load class of the damaged bridge along with the number of crossings which military vehicles can make. DERA are researching this problem in three ways Ballistic damage is most likely to occur from a near miss of a fragmentation shell. DERA tests show this gives extensive damage which is widely spread over the sides of the panels.
