Effect of Relative Rigidities of Shear Resiting System in Timber
Effect of Relative Rigidities of Shear Resiting System in Timber
(OP)
For flexible horizontal diaphrams (wood framing in single family residences) I have always assumed that the lateral shears transfer to the vertical shear resisting panels in proprotion to their relative stiffnes (as a function of their construction-widtn etc). Is there a "common practice" in the allocation of horizontal shear to vertical shear panels beyond the typical North-South/East-West analysis approach? We are currently allocating shear based primarily on the shear capacity of shear panel types that are installed along a wall direction and not really considering the effect of the relative rigidities of the panels working as a system. We are assuming that the overall shear distribution of the system averages out over the entire shear resiting system due to the inherent flexibility of wood framing. Are we missing a critical concern or method?

Second to the last paper entitled "Panel Discussion on Wood Seismic Issues" talks about an envelope approach using both flexible and rigid diaphragm theory.
