This paper proposes a new method for identifying structural dynamic decay, which is called acceleration information entropy (AIE). AIE function is built by combining bridge structural dynamics theory with entropy theory. AIE is closely related to the acceleration of information of the dynamic response of structure. This article also uses the finite element software to analyse the transformation law of AIE in the concrete beams in the event of structural elastic modulus dispersal, decrease, etc. When elastic modulus decreases, AIE increases. The more disperse of the structural material elastic modulus is, the greater AIE would be.
