Prestressing - Relaxation Coefficient in accordance to AS5100.5

Question:

Hi,

Is there any way that we can model the time dependent effects in regards to prestress relaxation in accordance to the Australian standard - AS5100.5? Further to this, is there an option for accelerated steam curing of concrete and the associated relaxation of strands stemming from this? AS5100.5 simply stated that an allowance at 0.8fp of 7% to 10% shall be made for relaxation during such a case.

Thank you. 

Best Regards, 



Answer:

Hi,

At the moment, it is not implemented in midas Civil. I think it will be included in a new future. For now, how about using user-defined relaxation function?
