(load bearing steel frame) (wooden shearwall)
(not braced)
greetings..
Is it ok if the beam in the load bearing steel frame(not braced)will not be connected to the wooden shearwall supposing the lateral nailing requirement of diaphragm to shearwall is already satisfied in the shearwall portion.Is the wooden diaphragm at the gap between the load bearing steel frame and wooden shearwall is critical for tearing off.( if is critical.. how will check the diaphragm tensile and shearing capacity in this case?)

You have steel framing and wood shear wall side by side. You want to put a wood wall on top of the steel framing that will bridge the gap between the steel and wood. If I am picturing this correctly, the horizontal diaphragm will be connected to shear wall [spacer boards, top plate, nails, truss ties, etc.]. At this point the shear load is transferred to your vertical diaphragm. I believe this would minimize any shear load going into the steel framing. Calculate the horizontal shear that is distributed to this wall. Divide this load by the length of your shear wall (steel + wood). This is the load that would have to be resisted by your vertical diaphragm. Another way is to desing an angle that is attached to your steel framing and wood shear wall (at the top). This would be like a short drag strut. With this configuration you would have a wood shear wall with a line load at the top and a point load where the steel frame attaches to the wood shear wall.

Im bit confused on on (steel + wood) part. Will it not be right to just divide the load by the length of the wood only? Or this is done in order to computed the shear to be transfered by the drag strut as point load to the wooden shearwall. thanks again
