RE: Replace a W-Girder with a Joist-Girder
You don't provide enough information here to allow a reasoned answer.
RE: Replace a W-Girder with a Joist-Girder
Thanks. You are right. I didn't provide enough information. I will give you some details:
What I would like to do is to use Joist Girders instead of W Girders to make the frames I design more economical. I start doing some research and I saw this information about TECHNICAL DIGEST #11 - DESIGN OF JOIST GIRDER FRAMES (July 1999), "Joist Girders provide an economic structure you may not know of the added economy afforded through the use of the Joist Girder/Rigid Frame concept."
But I have some doubts even before I start using them and the reason is this:
I tried before to use Cellular Beams instead of regular W Beams for the rigid frames the company I work for is designing, but talking to a the Midwest Regional Manager of
CMC Steel Products he discouraged me, saying that his company is not interested in providing small amounts of Cellular Beams. They now have a lot of work for areas like
Las Vegas, to give me an example.
My question is: from your experience what should I do succeed this time in my attempt to replace the heavy W Girders with Joist Girders?
RE: Replace a W-Girder with a Joist-Girder
I don't see a problem.
RE: Replace a W-Girder with a Joist-Girder
As EOR you will need to do your homework on providing the right info to the joist manufacturer and coordinating details.
This Vulcraft catalog might give you some useful information to start with; see p 78:

JKW05,
Thank you for your useful information
UcfSE,
I am sorry, but I am not sure what LFRS stands for

My answer to UcfSE is YES.

show gravity loads. Doesnot meen that joist have no axial capacity. But I will like to see how joist manufacturer being designer too handles this. By the way RICI, economy of joist sometime cause vibration problems.

"Designing with Steel Joists, Joist Girders, and Steel Deck"
Click on the link in that page just above the title of the publication I referenced. It is not expensive and provides some details and design guidelines for using joists and joist girders in moment-resisting frames.
You may also check out the Steel Joist Institute Catalog for additional information or requirements.

If I will use the Steel Joist only as a Roof Girder,
I hope that the vibration is not a problem anymore.
UcfSe,
Thanks. I will check out "Designing with Steel Joists, Joist Girders, and Steel Deck"
Civilperson,
Yes. The increase in depth is an issue. Thanks.
