For a given loading, the ratio of the expected failure load of a laminated timber bridge and the analytical failure load obtained by assuming the modulus of rupture (MOR) and modulus of elasticity (EL) to obtain their respective mean values, is called the reduction factor. The value of this factor is always less than 1.0, and depends on the transverse deflection profile of the bridge. A procedure is presented in this paper by which a realistic assessment of the reduction factor can be obtained by using test data for the MOR and EL for any species of wood.
