In Timber Engineering Notebook No. 3 (part 1 in this sub-series on platform frame construction)
, the composition and terminology used for platform timber frame building structures, and the structural engineering checks which are required to verify the adequacy of the vertical load paths and the strength and stiffness of the individual framing members, was introduced.
This Timber Engineering Notebook introduces the engineering checks for overall building stability and the stability checks required for the wall diaphragms which provide shear (or racking) resistance to a platform timber frame structure.
Robustness and disproportionate collapse design considerations for platform timber frame buildings will be discussed in part 3 of this sub-series.
