I've used 3D BEAM188 element for bridge deck model. At first I've created sections by using ANSYS custom section command but I can't model reinforcement in that section and how can I consider reinforcement in that section? By the way there are PC tendons in the bridge deck. How can I model this matter? Is there any other procedure to model prestressed concrete bridge deck? Can any one provide me some related article about this matter? By the way I'd like to perform prestressed modal analysis of that Bridge but I couldn't consider the prestressing effect. So how can I consider prestressing effect? Can anybody help me about this matter?
Effect of pre stressing is usually represented by increasing compressive strength of concrete in the direction of prestress. In the direction perpendicular to pre stressing, compressive strength will be at usual level. In a old bridge, the progressive development of concrete strength with time may also need to be taken into account.
Dear Mr. M.s.I. Choudhury,
Have you reached to the way to consider the prestressing in Ansys 16?
Please let me know as i also searching for this point and don't now how to apply it in Ansys 16?
in earlier version, it was possible to apply prestressing by input an initial strain to link8 but the new version hasn't this option.
Regards,
Mohamed Fawzy
