"Grade Beam" indoors
"Grade Beam" indoors
(OP)
I have situation where I may need to design a somethign similar to a grade beam that would be indoors to support heavy traveling equipment.
In a case like this is there any need to go below the frost line or is down to suitable soils ok?
Would it be advisable to use small piers, say at 10' centers to support the grade beam rather than support the beam directly on the subgrade or prepared subgrade.
This is conceptual at this stage.
Any advice or input would be great.

what if your foundation is near an exterior wall?

I just have intuitive concerns with only going down 12" or so in an older existing building. I have yet to look at the site, but I'm uncertain as to what kind of fill is going to be present under the existing slab. I'm not sure I'll be able to look at he fill and say "that looks okay".

I guess really waht we are talking about here is not really a grade beam if there are no supports other than the soil, correct?

If so, it would be very appropriate unless you can span the grade beam to existing footings, which you seem to say that you can't.

If this is a metal building (PEMB) you may have cross-ties or hairpins at the mainframe locations to consider in the design too.
Just a thought.

sorry to blur the lines.
I was thinking originally that maybe I would install piers and span the grade beam between. I think this is not practical.
I think it will wind up as a BOEF....Beam On an Elastic Foundation
or a
GBOEF....Grade Beam....

Mike-
Should I encounter Hair pins in the excavation am I screwed or can I incorprate them into the new beam?
Also, I'd like to ask again if others think a BOEF is an approapriate approach?
The beam will essentially bear on soil and have a series of moving loads.
