I'm referring to Eurocode 5 (in particular Annex B & C of EN1995-1-1 2004 - Design Of Timber Structures, Common Rules And Rules For Buildings) where formulas for assessing the effective stiffness (EI_eff) of 3 built up members is given in B.2.
I was wondering if anyone familiar with the method has any relevant example calculations (published examples or just your own calculations you'd be willing to share) where you're using the method for assessing more than three members stacked together?
My design situation is multiple wall studs built up (for example 4/5/6 etc normal studs nailed together to form a single built-up member under axial load in multistorey timber shear wall construction. I'm no having much success in envisaging how the method and formulas presented scale to other common cases with more members being added together.
For example 4-140x45mm studs nailed together to form a 140x180mm sized built up member.
The design guidance I'm following offers this as one way of assessing the effective EI of the studs for axial buckling checks for the shear wall chords.
Thanks!
