Dear All,
I have been trying to calculate the bending moment redistribution on continuous, steel fiber reinforced, beams.
The idea is simple, introducing to the ANSYS model elements, with lowered E-modulus, according always to the evolution of the cracking observed on the actual tests.
I tried initially with solid 65 and a 3-d model but this material is not compatible with the bending moment (BM) calculation by ANSYS.
I then created a model with BEAM3 element and obtained the BM diagram (Line element solution).
Here comes the tricky part: when i implement new elements with reduced e-modulus i get the same BM-graph. That is obviously not correct since my beam is a continuous supported beam and thus a moment redistribution must be noticed. (Of course I updated my element table after the 'solve>current LS').
What can I do? How can I make it work?
The best,
DSav
