Modelling an Unbonded Prestessed Tendon

[schaf218]

Hello all,

I am doing some dynamic modelling and I am trying to figure out how I can model an unbonded prestressed tendon used to apply an axial load. I have tried just using an axial load, but it fails to account for the increase in axial force due to deflection of the column during dynamic analysis.

Any suggestions?

You need to model the tendon itself. In this PEER 2008/06 report (free to download) you may find information you need.
