Folks,
I am reviewing a design calculation for a braced frame in SDC D. The braced frame columns are supported on drilled piers and there are grade beams connecting the pier caps between braced frame columns.
However, the grade beam has only been designed for moments due to gravity loading and axial load induced by 0.1 Sds P.
The eccentricity of shear from the base of the footing to top of footing and its subsequent transfer to the grade beam has not been done. I believe that the moment due to the eccentricity of the lateral force from the brace to the bottom of the pier cap should be transferred into the grade beam. This will produce additional moments at the interface of the beam and pier cap. Am I correct in making this statement?
Also, I have looked to see if there are good examples that show how the grade beam tied to pile caps is designed. I want to do one by hand to get a better feel. Any references?
Thanks
