Paper explains in light of recent research into concrete stress-strain relationship in compression, flexural behavior of statically indeterminate reinforced concrete beams when loaded to collapse; based on concept of concrete as strain-softening material, it is shown that length of beam can continue to rotate when moment is falling off and that rupture will not occur unless energy balance in beam ceases to be satisfied; possible development of true collapse methods for analysis or design of indeterminate reinforced concrete beams is discussed.
