if the area of tensile steel reinforcement is
doubled the moment of resistance of the beam increase
about​

Answer 1

Answer: If the area of tensile steel reinforcement is doubled, the moment of resistance of the beam increases only by about 22%. Steel reinforcement bars or rebars are used to improve the concrete's tensile strength, as concrete is very low in tension but strong in compression. ... This is called the internal resistance moment..
