Plank Camber

Camber is defined as the upward deflection which occurs in prestressed concrete plank due to the net bending resulting from the combination of movements due to stressing forces and dead loads.

Generally, the span of the plank and the superimposed loads carried by the prestressed plank will increase its camber.

The anticipated camber at the time of the transfer of the prestressed force can be computed. The final camber of the plank may be two or more times the initial camber computed due to creep and time related strains in concrete.

Adjacent prestressed plank of different lengths, strand patterns or openings will inherent different camber differences.
