Superelevation

The term “camber” refers to the amount of pre-deformation that, for example, a glulam beam receives intentionally during manufacture in order to compensate for the deflections resulting predominantly from permanent loads in the installed state.

The use of a cant has the advantage that smaller cross-sectional dimensions are possible. This is because these are often dimensioned stronger than the load-bearing capacity requires due to the limit values for deflection that have to be complied with.
