Corbel action on Column analysis
Corbel action on Column analysis
(OP)
I have a doubt that how the RC corbel action(Tie action) is applied to the RC column analysis
Is it correct to applied it as a Pxav(P- vertical action on corbel, av- distance between root of corbel & line of action) or as a Tie force which counteracting the column compressive load. Consider that the RC corbel and RC column are non precast element
thanks

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.

My point is that no moment is transferred to the column when a strut and tie is used as the forces only are axial in the truss which directly transfer the corbel vertical load to column as a compression load but no moment.

I think you are getting 'stuck' conceptually and it may be best to think in terms of 'external' applied load/s causing 'internal' forces/stresses.
So, as IDS states, you have an "eccentric vertical load" (this is your 'external' load x eccentricity = 'externally' applied moment), and your strut and tie forces are your 'internal actions' to those external applied loads.

Also cancel out in the sense that the net impact of the tie on column axial force is zero beyond the tie itself.
Any internal analysis that is complete will produce results consistent with the external results. The answer does not depend on the method.
