Design Reference/Example for Grade Beam linking two Braced Frame FTG?

Design Reference/Example for Grade Beam linking two Braced Frame FTG?

(OP)
Hi Guys,

I am just wondering if there is any design example/guidance/reference I could look at for the design of the grade beams which tie two isolated braced frame footings?

What I wanted to know is that:

Do I need to design this grade beam with some moment and shear capacities?

Any information would be appreciated.

RE: Design Reference/Example for Grade Beam linking two Braced Frame FTG?

If a hinge is placed in the center of the grade beam, (expansion material with the steel contiuous through the center of the beam), then no moment strength is required. Alternately, a rigid connection between the two foundations needs both moment strength and shear capacity.  The tie requirement is axial and the other forces can be taken in the foundations alone.

Thanks Civilperson.

So generally what did we do in practice?
