Modeling Wood Shear Walls as Plates in RISA 3d

[jgeng]

Looking on advice for modeling wood shear walls as plates in RISA 3d. I know the program has a wall module but it seems to be limited to rectangular shapes which I don't have on my gable end. I would be content with just accuarately modeling the force transfer in this case. Should I use a shear modulus that includes fastener slip? and what modulus of elasticity? thanks

Also what releases should the plates have? And does anyone have advice for modeling a diaphragm composed of 5/4 decking planks or 2x10 hoists? How would you calculate the modulus ir effective modulus of rigidity? Thanks
