Problems With Ceiling In Renovated Church

I have a well insulated garagegarage (2x4 with batt) with about a foot of blown in insulation in the attic. When the wind blows straight line at the side of the garage, the corner of ceiling and wall build up with ice. Any ideas to help the issue?

Hi all, I need some critiquing: I need to make what appear to be partitions. The walls of these partitions need to be elevated off the floor by 9". The walls need to be 5' high themselves (floor to top of wall = 5'9"). The walls longest span will be 11' with two 4x4 fir floor to ceiling post midway through (16" on center). These walls will be supported primarily by 2"x2"x1/4" square steel tubing. This square steel tubing will be lag bolted to the floor and ceiling. The walls will be traditional 2x4 construction that will be bolted to the square tubing at the ends. I've done some sketching of it in Sketchup: [ATTACH]27315[/ATTACH] Here is what one of the support posts base will look like (each post will be a two piece unit). You can see that there will be added support for the wall. [ATTACH]27316[/ATTACH] Then just to clarify; the upper part of the post will be bolted to the lower section (i don't show the bolt pattern to clearly but I'm aiming for at least 5/16 bolts x 4 for each). [ATTACH]27317[/ATTACH] This is an idea dreamed up that would incorporate both metal and wood into building elevated wall partitions My issues that I'm having are: 1) Is this going to be strong enough to support the wall and at the same time be safe? 2) My main concerns are in the floor to ceiling attachments of the 2x2 sq tubing with the 1/4" plate welded at the bottom and top. \ The ceiling 2x6 joint construction. I am considering using a double 2x12 bridge block securely boxed in place, then using 5/16" x 3" lag bolts to attach with. The floor is supported with an engineered I-joist assembly. I could lag bolt into the floor but what is the best way to do this? I need some advise. Thanks for any help: Brad
