Are the requirements for the minimum horizontal steel (0.007Ag)in a masonry wall for wind design the same as for seismic loading. I looking at a masonry wall in 130-mph wind speed.
The connection is similar to Fibure 8-18 on page 8-24 of the AISC Manual 13th edition. The contractor wants to add a channel to each side of a tube column. The web of the channel will be next to the column and the flang will be flush with the column.
If I need to weld two members together and has a large radius, can I specify a backer rod to fill in the void provided the weld attaches the rod to both members and extends over the top of the backer rod?

For a RV, truck, or equipment parking cover, the metal roof deck spans over the roof purlins. The roof purlins span between the roof beams, and the beams cantilever out from the columns forming a ‘T’ shape. If there are more than two sets of beams and columns across the width of the canopy...
I have seen on some websites either single or double 'C' Shape Member back-to-back. The beams and columns were attached by steel plates and bolts to create the building shape similar to PEMB Frames. They were used on garage, sheds, and barn size structures.
Thank you for your responses. I am on my way out to check the crack. Also, I have a call into the floor deck manufacturer to see if they can be any help. I will be looking in the blue book for a concrete repair contractor for their input.
Changing the subject alittle. You have talked about a canopy adjacent to a structure. Also, a canopy as an open structure. How about a canopy which stores RV's, etc... Eventhough there are no exterior walls, the wind would not necessarly pass by. The obstructions (RV's) would cause the wind...
