interior shear wall
interior shear wall
(OP)
We are designing a wood frame storage building 200 ft long 64 ft long 16 ft ceiling. There is a 22 ft door in each end. The available shear wall length is thus 42 ft at each end. My numbers give me a required shear wall resistance of over 700 plf at each end. One possibility to reduce the shear load at the ends could be by adding a shear wall inside. However that interior shear wall would have to bear more than half he lateral resistance. And that does seem too make much sense
Any comments would be appreciated.. Thanks

RE: interior shear wall
With the interior shearwall you could also check the requirements of a rigid diaphragm to see if you qualify. It's unlikely, but would allow a more favorable distribution of stresses.
If the interior shearwall really doesn't make sense, 700 plf isn't unmanageable by any means.
RE: interior shear wall
I don't see any particular problem with designing for 700 plf. Is the roof framing wood trusses/wood sheathing diaphragm? Has joist girders with light-gauge decking been investigated. In my (limited) experience, that's the more typical option for a roof this size.

RE: interior shear wall
Out of curiosity, how is the frame constructed? Is it heavy timber construction or something else? I'm simply asking to learn, as, in general, buildings of this approximate size, shape, and use have always piqued my interest. Thanks.
RE: interior shear wall
The shear in the end walls would be close to the limit for a wood-based panel on S-P-F framing. The factored shear resistance for a 15.5mm panel with 3" nails (3.66mm dia.) at 50mm centers is 15.3 kN/m or about 1050#/' or a working load of 700#/'.

Archie, This building certainly piqued my interest too. Never did a building this long before. It’s long and high and wide open.
You fellows may have more to see when you check the quick sketch attached.
Thanks for the responses.

My hands are not as fast as my brain, or is it the other way around?
