In a simply supported RC beam when i give displacement at a node in abaqus, in order to draw the load displacement curve, i should plot U2 vs CF2 OR U2 vs RF2. I'am asking this because i'am getting CF2=0 while u2 is giving non-zero values
probably, the node for which you plot the displacement-reaction force curve, was unconstrained in the Y-direction, otherwise there must be a value for the force at the node!
