Comparison with ABAQUS– Uneven distribution of reinforcement in x- and y- directions

Accurate prediction of moment redistribution due to uneven reinforcement

Cylinder subjected to ice load-UR outer vertical reinforcement

Non-Linear, outer Z-reinforcement, Max UR=0,968Linear, outer Z-reinforcement, Max UR=1,2

Omfordeling av moment i x- og y-retning når armeringen økes til 10-gangern i den ene retningen. SD og Abaqus er sammenfallende, den blå kurven er lineærelastisk, som ikke tar hensyn til faktisk armeringsmengde.
