This Robertson catalog is definitely the closest I have come to a match. In my case, the cold formed metal sections have coating on both sides, I think that made my gage measurement bigger than the 14 to 18 gage range shown in the catalog. However, this is a great reference. Thank you JAE!

Trying to find design information (ex: load table) for an existing roof deck using long-span cold formed metal deck sections. Refer to attached pdf file showing a sketch of the metal deck profile and a picture of the existing roof deck. Any tips, info, or recommendations for manufacturers would...

Brad805: no we have not, we don't have access to those members yet to take field measurements. But yes, that would be a good idea also.

Alright let's try this again (maybe third time is the charm). The correct pdf file is attached.https://files.engineering.com/getfile.aspx?folder=81720986-8c4a-47d3-a356-ae40c47b4881&file=partial_Roof_Framing.pdf

Alright, thanks Ron for looking into it anyway! The pdf file in my previous post was not the correct. I have attached the correct partial framing plan showing the #200 Bulb Tee callouts.

Jayrod12: Thank you for sharing that info; very helpful. This existing roof framing that I am working with calls out #200 BULB TEE @ 3'-0" O.C. typ. (see attached pdf file). This building was designed around 1963, there may have been a particular manufacturer that carried these shapes. The dwgs...

Hello, Does anyone know where I can find design info or sectional properties on these two types of High Strength Bulb Tees: #200 and #258? Thanks.

thanks a bunch dik... that was helpful.

thanks dik for the response. Is that 1.5psf for the whole 9" insulation? Do you happen to know the link to where on Dow-Corning web site they keep this info?

Trying to estimate dead load for 9" Batt insulation for an existing roof framing analysis. What would be a good reference to use to come up with a good estimate? Thanks.

I have an email out to them at the moment asking about that; waiting for a response...

JAE: yes I saw the same data on SJ167 in the SJI 1948 load table. So we should be in the clear with that one. I did reach out to SJI via their "Joist Investigation Form" and they were very helpful and responsive. They sent me a copy of the load table for CECO's Long Span joist (see attached)...

Here are the ones that I am looking at right now: No.167 (Steel Joist) No.184 (Long Span) No.207 (Long Span) No.3011 (Long Span) They seem like proprietary shapes and sizes.

Thanks JAE for replying to my post and for sharing that catalog. This 1967 catalog does not go far back enough to cover the case that I am dealing with (1948/1949). However, I have other existing buildings that will be looking at, built within this timeframe and there is a good chance that I...

This is probably a long shot but thought I would try anyway. I am working on a structural evaluation for an existing building, built between 1948 and 1949, with a roof framing system that includes steel bar joists. Based on the existing engineering drawings the bar joists are by CECO steel. Does...
