Finally, a barn built with our new connectors

[flusher]

Just out of curiosity, did your county building dept. make you get an engineering design package for your construction before they would issue a building permit? If so, how much did the engineering design cost?

Last May-July I had a steel frame/metal sided shop/garage built on my place almost the same size as yours (24 x 42 ft with 12 ft walls, two 10x10 ft roll up doors, one man door and one window). The building cost about $16,500 and the 6" thick concrete slab about $8,000. The building cost included about $1000 for the engineering design package.

The contractor used lotsa self-tapping screws, especially in the roof trusses (6's and 12's). Just a quick look at the attachments in this thread makes me wonder if there're enough fasteners holding your structure together.

We're in Texas. /forums/images/graemlins/grin.gif

We do get building permits for the county but it's for tax purposes and not for inspections. They want to know what you've got so they can valuate the property.

We're going to get engineering done so we can specify just what our connectors can do and how. Right now I'm in the process of perfecting the design as best an old rube can.

Then we'll turn it over to the experts. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

I appreciate you concerns about screw count but I'd have to see your design versus mine to have a better idea where you're coming from.

Your design from you post sounds like one Mueller has that they don't sell much of out here. http://www.muellerinc.com/buildings/catalog.php

I looked at their site and couldn't find their links to that product. Basically what it consisted of is connectors for specific joints. The building has to be designed by them and then they supply the connector. But when I was looking at their connectors at their store in Sherman Texas they hadn't sold any of the connectors and had no local examples of the construction.

If you have the time I'd appreciate pictures of your barn with details of it's construction.

One of the wonderful things about TBN is we get to learn and share.

Welcome to TBN Chris, glad to see you found your way over here from that nasty old welding site. /forums/images/graemlins/grin.gif /forums/images/graemlins/grin.gif

If you get a chance cruise down to "meetings and get togethers" and cruise through the "norte tejas get together" and related threads. You would have had a ball on that one and I'm personally going to have to insist you become a regular attendee of our spring fling thing. (hint hint Jim and Bird)

Here are a few photos of my shop/garage.

That's a nice looking barn you have there.

At first all the screws at the joints confused me. But then as I studied the layout and construction I think I understand their reasoning.

Correct me if I'm wrong but I believe the bulk of your framework is sixteen to eighteen gauge. That would explain the need for all the screws.

I would really appreciate any information you have on the gauges of the different components.

As we're finishing up the original barn I'll post pictures of it so you can compare techniques for us. I'd appreciate your comments and critiques.

Here goes:

The frame is 2x3 inch Allied Flo-Coat rectangular tubing, 14 ga.

The siding is 26 ga Reyerson Hi-Rib 4. No purlins needed for the side walls since the siding corrugations provide the stiffness.

The hat channel (for roof purlins) is 1-1/2" 18 ga McElroy "Mac-Girt".

Fasteners are #12 and #14 self-tapping screws, 1" long.

The roof pitch is 1.5:12.

The structure is designed for 75 mph wind load, exposure B; seismic zone 3.

The roof design live load is 20 psf.

The materials used in this design are pretty standard in the metal structures business. The reason for the multitude of fasteners is to handle the loads imposed on the frame by the design requirements, which may be a lot different in your neck of the woods.
