Zman1,

All of that information is proprietary and is only available from Butler Manufacturing Company, Kansas City or maybe a Butler builder.

You will really need to provide a lot more information.

Location of the building.

Date of the building erection.

Butler builder who built it.

Code it was built under.

Do you have original drawings from Butler?

span of the truss purling, depth of the truss purlin.

more information may be required, including original Butler order number.

Thanks guys,
There is an MVP on this site AHJ1 who seems to have the properties in his possession. I was hoping he would see this thread. I am fairly new, but is there a way to contact him directly through this site?

There is no direct messaging.

jimstructures is well versed in those buildings, I would trust what he's asking. It's possible that the number you noted is just the member number specific to the job as opposed to one that signifies anything about the purlin. Similar to a joist tag.

Zman1 & jayrod12,

If I am not mistaken 530205 is a standard Butler part number for Truss Purlins, i.e. proprietary Butler roof joists.

We really need the span and depth of these truss purlins as well as the erection date of the building to say much more about the parts.

There was a major change in Butler truss purlins in the mid to late 2000's (????) so the dimensions and dates will tell a lot about the part.

I assume you don't have original Butler erection drawings for the building as they would give a lot more information.

AHJ1 may have retired from Butler and I sincerely hope his boxes of historical information have been saved.

You need to contact Butler Manufacturing Company and ask for the Engineering department or at least a Butler builder.

I have the drawings, joist tags along with detailed field notes on these things. I was on site on Thursday. They are 50' span and 29.5" deep. The building is from the late 80's. The top and bottom chord are a custom cold formed shape with 1" tubing as the web members. Thanks for the input, I will contact Butler.

Zman1,

From the date information and the depth dimension, you probably have any original Butler Landmark building. On the original Butler drawings there should be an Order Number, normally in the lower left hand corner, and the name of the Butler builder who sold and erected the building.

Be sure to ask for somebody with experience in original Butler Landmark buildings. Make sure they are not talking about Landmark 2000 buildings, they are newer and different dimensions, materials and capacities. The buildings should have been designed for the local loads and conditions.

Look at the drawings and confirm they are Butler drawings and not Architect's translation of the building drawings. The drawings may have the loads the building was designed for and the Code used. Maybe MBMA 1986.

Zman1,

The handle name of the MVP is AJH1 not AHJ1.

Sorry I took so long to post this correction.
