Progressive collapse resistance of RC beams - ScienceDirect

Due to higher compressive and transverse reinforcement in the special frame compared to the ordinary frame, concrete crushing does not occur in the core of the special frame beam. The beam reaches equilibrium at around 36.95 in. (939 mm), which is almost 8 in. (203 mm) smaller than that for the ordinary frame for the same axial stiffness.
