Thanks. It appears the entire connection calculation process for NDS is to provide a result in ASD (safety factor already 'applied'). I don't see a way to get back to a nominal capacity. I'm not sure when it occurred, but looks like LRFD adjustment factors were added to AWC-NDS when the LRFD...

Hello, I am working with some data calculated via the 2018 AWC-NDS. In looking lateral capacities for wood screws (my question applies to other scenarios as well), the NDS calculates the ASD capacities, and the LRFD capacities using the basic equation in Table 11.3.1 Unfortunately, for the...

Thank you for the response. Yes, there are many applications in snow country that utilize snow guards on the roof to prevent liability issues with snow sliding off and doing personal or property damage. In the California Tahoe area, we see snow loads of upwards of 300lbs psf which creates a...

Looking for design guidance on the clips that attach purlins to other purlins or beams. - Is there a requirement or standard on what gauge and yield strength these clips need to be? - In general, are they only resisting uplift loads and potentially side loads? - I've generally seen them as...

Hello. Trying to evaluate drag load capacities of metal roofing over plywood roof deck. This would primarily due to high snow loads wanting to slide metal roofing off the roof deck. Up near ridge we would run a particular number of fasteners to resist these drag loads. It appears we need to...
