We’re building a shop ourselves and keep failing the shear inspection because we don’t have the engineering results to send to the city engineer. He said our wood supplier should be able to draft that with some special software but they can’t apparently, so I need to figure out how to get that done.
The header is basically two 2x10 Douglas fir boards sandwiched between two 2x6 Douglas fir boards. I’m assuming they need to know the failure point and distribution over the 108” span, but I’m not certain.
Anyone know where I can get this information? I really appreciate your help!
