z Steel decks of bailey bridges are deformed and needs proper fixing, z Steel I-Girders are all corroded, and z Seven bridges are posted with 15 tons load limit while one bridge is posted with 5 tons With respect to the military use of a bridge, each military vehicle will have a Military Load Class (MLC), which is a function of its weight, width, speed of crossing etc.
For assessment of existing bridges, load rating is usually performed to assess the capacity against vehicular loading. Bailey bridge components can be assembled in seven different configurations to efficiently accommodate a wide range of span and capacity requirements. Panels, the primary Bailey components, are pinned together at the job site to make girders of any length. A Bailey bridge has the advantages of requiring no special tools or heavy equipment to assemble. The wood and steel bridge elements were small and light enough to be carried in trucks and lifted into place by hand, without the use of a crane. The bridges were strong enough to carry tanks.
The failure load is increased until the bridge fails under the defined failure criteria, such as deflection limit, yield of steel reinforcement, or concrete failure (tension or compression). The load capacity of the bridge is 40 tonnes and vehicles going beyond this load limit can prove dangerous for the bridge. The load carrying capacity of a Bailey Bridge (or any other bridge) will depend upon its span and its type of construction. Abstract.
