Plastic Analysis question

Plastic Analysis question

Plastic Analysis question

I am trying to analyse a frame plastically but have run into trouble, I have selected a critical mechanism which has given me the highest moment. I am now trying to check the moments at non hinge locations in order to check that the moments there are not surpassing the moment of resistance for the beam/column. I am struggling to know what direction the moment is assumed to be, please find the attachment with the drawing and arrows without arrowheads indicating an unknown direction.

Many thanks

RE: Plastic Analysis question

Your moments occur at connection points. Use end plate connections to develop the full section moment and shear. Also check for load reversals (shakedown).
