Not even close. AA allowables for shear in webs for building design is 12
ksi. Tensile allowable is on 19 ksi. For welded structures these numbers
go to 7.5 ksi and and 11 ksi. Values are lower for bridge type
structures. Shearing yield and ultimate stress are 20 ksi and 27 ksi. Get
hold of 'Specifications for Aluminum Structures,' from the Aluminum
