Indian standard code of practice for Prestressed Concrete Design IS 1343 1980 had table number 12 for the design of Unbonded post tensioned concrete for varying l/d ratio and reinforcement index. However, the same has been removed in the recent revision of IS 1343-2012. Nothing is mentioned explicitly why it has been removed?
Does that mean Indian standards does not allow Unbonded PSC design in INDIA?
hello dear friend
if you use ADAPT software to model prestressed design, you can find it there
It is impossible to prevent using the unbonded tendon in prestressed concrete members. I think that the code used another methodology rather that supporting on table 12.
Dear Nazar
Thank you for your answer
I understand what you are saying but it becomes very difficult for designers to verify their design or even follow the code if direct tables or equations are not present in the standard code of practice.
Could you please send me table 12 or any equation for that purpose?
I agree with Dr. Nazar, because both AASHTO LARD 2012 and ACI 318 2014 have provisions for unbonded tendons
Good answer Nazar K Ali Oukaili .. and Agree with Abbas AbdulMajeed Allawi ....... Good question.. Following...
