I am attempting to model a pretensioned concrete beam in ansys by varying prestressing force along the Straight Pre-Tensioning Strand.
During the experiment, the beam was fabricated segment by segment. The applied prestress was then released decrementally after each concrete segment.
The results of the distribution of prestress should be similar to the attached Figure 1.
However, in the finite model, the beam model is already been fully constructed.
I am trying to consider the prestressing force as push in pressure at the both ends of the strand.
Hence:
How do vary the pretensioning force for each concrete segment ?
If possible, please help me to provide some background source.
Thanks
There is probably cleaner way to do this, but you could also try varying temperature of the strand to "fake" prestress. This would of course complicate things if you need to also consider temperatures in the analysis.
