How to model unbonded post-tensioned tendon in concrete slab in ANSYS
Hi, everybody.

I am Haider, from Baghdad, Iraq. I am currently study in civil engineering and taking my final year project for degree graduation.

My thesis title given by supervisor is to use ANSYS to modelling a 4m X 1.6m one-way simply supported prestressed concrete slab with unbonded post-tension method, and then to study the deflection behavior.

After that i was request to perform lab experiment to use an actuator machine to carry out a test so that the ANSYS result can be verified.

I am struggling for around 4 month already, but still not yet any improvement. Due to lack of information in my university, and also do not have lecture skill in this field.

The main problem I am facing now is how to modeling the curved unbond tendon(strands) (which is the best element?) and how to perform the contact between the tendon surface and concrete, since I only know how to sketch out the concrete slab and steel bar separately in ANSYS.

I am currently using ANSYS v10.

Do teach me how to do it, I am very much appreciate, and I am hopping for anyone to guide me for the ANSYS usage.

Thank you very very much!
