Dear all
I want to exactly know what the effect of low temperature on the strain at peak is. In an article, it has said that, as the temperature decreases, the strain at peak increases (Fig 1) but in other article, it has shown that, as the temperature decreases, the strain at peak, generally, reduces too (Fig 2).
I don't know which one would be correct.
Do you know any other references?
Dear Masoud Hasanzade
Both increasing and decreasing of the concrete strain under low temperature have been discussed in the following paper:

Dear Mehran Shahpari
Thank you for your understanding and answer
It was so helpful
