How to model unbonded post-tensioned tendon in concrete slab in ANSYS
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!
this is dehghani
we have pt slab in najaf in iraq.
we install slab postention bonded above 1 month later .
if u need information of this slab can come in najaf kofe and see.
