A practical method for calculating the flexural rigidity of reinforced concrete members under short-time loading is proposed. This method has been developed and refined to achieve both simplicity in use and a representation of actual behavior that is as realistic as possible. Extensive comparisons of the calculated deflections have been made with the results of 434 tests of actual beams, providing final confirmation of the validity of the proposed method.
