A T-beam behaves as a rectangular beam of a width equal to its flange when the neutral axis lies within the flange, typically when it is between 1/3 to 2/3 of the rib depth. This condition ensures that the compression is fully taken by the flange, allowing the beam to be analyzed as a rectangular section for simplicity in certain conditions.
