Greetings,
My professor has asked a question with valuable points about a topic in RC structures.
The question is:
Why is there a limit on the diameter of positive bending bars in simple supports and inflection points of concrete columns, but there is not any diameter limit for negative bending bars? the answer is not for compression or natural confinement.
He says the answer is not that simple and probability for someone to find it is insignificant.
It was asked during the development bars lesson.
Kind regards
