Effective Length of Timber Rafters in Compression
For the design of timber rafters in compression the traditional interaction formula for bending and compression stress does not take the stiffness of the bracing system into account. An additional criterion is proposed from which the number of trusses supported by one braced bay may be calculated. Analysis of diagonal bracing systems shows that the rafter will always buckle, for this bracing system, with a half wave length of approximately 3 m. With bracing frames, strength and not stiffness will almost always be the criterion.
