5.3.2 Members subjected to compression at an angle to the grain

This is an ultimate limit state condition and using the empirical relationship developed by Hankinson [5] the failure strength of a wood-related product when subjected to a resultant compressive action at an angle a to the grain, fca, as shown in Figure 5.7, can be writtenin terms of its strength parallel to the grain (fc 0) and perpendicular to
