Hi
Is there a difference between Ground beam and Tie Beams? or are the different names for the same thing?

RE: What is the Diffrence between Ground Beam and Tie Beam?
In masonry construction, a "tie beam" is an intermediate beam used at floor levels and roof levels to provide lateral continuity of the masonry and to "tie" the tie columns or end walls to prevent lateral movement. In wood or other framing systems a "tie beam" (also called a collar beam or collar tie) is a beam section that prevents two structural members from spreading apart, such as roof rafters.

Much appreciated!

Grade beam: soil level beam transferring loads delivered by superstructure above, or expanding soil below, to discrete foundation elements (piles/footings).
Tie beam: soil level beam connecting two or more vertical load carrying elements -- usually columns -- for the purpose of stabilizing those elements laterally, particularly in the context of high seismic motion.
Often, you'll have grade beams around the perimeter of a building supporting the exterior walls and tie beams in the interior stabilizing isolated column foundations. When tie beams are required in the interior of a building, usually the perimeter grade beams will also serve as tie beams. And, of course, you sometimes have grade beams in the interior of a building as well to support interior bearing and shear walls etc.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

Thanks for the tailor made explanation :)
small followup: can tie beams not be at grade?
RE: What is the Diffrence between Ground Beam and Tie Beam?
Tie beams can definitely be at grade. Most are I think. I only wrote "at soil" level so as not to preclude the case where your tie beams are a story or more below grade in a structure that includes a basement. Most folks consider grade level to essentially equal main floor or the level of the ground outside of the building footprint. Perhaps "foundation level grade beam" would have been better terminology.
In terms of construction, I often see tie beams of this sort constructed as merely slab on grade thickenings.

RE: What is the Diffrence between Ground Beam and Tie Beam?
Although these terms could represent many differing applications, since you are...
I would refer to jimstructures comments as most applicable.
The "ground beam" would likely refer to a grade beam foundation or perimeter beam where, for economical purposes, this foundation system could be chosen where a 4' or frost wall is not preferred. (Believe it or not, we design many grade beam foundations for commercial buildings in Wisconsin.)
The tie beam may likely be referring to the tie-rod(s) encased in concrete. The steel tie-rods would be mechanically connected to the bases of opposing metal building columns possessing a considerably higher horizontal thrust that is too high for the typical hairpin to resist.
In addition, I agree with Koot:
Outside of the OP quote above, i cannot deny the other references to the terms.
