I guess all I'm trying to find is reliable eqn to determine the torsional stiffnes of a RC girder to do my Moment distribution (look at the pictura I'm attaching) the only difference it's that the moments at both ends will not be zero anymore, there's some moment due to the girder torsional...
I've been trying to solve a moment distribution problem where I have a two span continuos beam framing into girders. I know for a fact that when I set up my distribution factors and carry overs I can't ignore the fact that those girders provide the supports of some torsional stiffness, so they...
