Title: Moments in wood structures
I have seen an unbraced carport collapse under snow load.  I would not have wanted to have been underneath it.

Acie,
 
A lot of cities have standard fix details for patio covers and free standing 6 ft  fence for long time
they never change them, it does not have the capacity for today code
but they say is ok , you do not live under patio
even for attach one story garage
Thanks

List

     A city engineer told a client that he would sign off on a patio with Simpson CB at the bottom and Simpson CC at the top of six wood columns.  Patio is 20' X 40' with two rows of three columns. Wood beams connect the six columns.   As there are no shear walls or braces at least one of these connections, top or bottom must be moment resistant.  I have not been able to find any EER or other data showing these connections will take moment.  If any one know of any information this hardware making moment connections in wood share it with me.

Thanks
Acie P. Chance
