英文摘要	The energy distribution state of each stage of concrete cracking has been studied in this paper, which based on dissipative system characteristics, and combined information entropy theory with energy method. The entropy change function for different stage of crack stable and unstable growth is established. The element damage degree formula is deduced, which can be used to judge the stage of crack. Finally, the cracking process in a double span continuous beam is simulated by Midas/FEA to compare with other literature. The result suggests that the strain energy entropy function proposed is capable of well describing the evolution law of concrete cracking. © 2017 Taylor & Francis Group, London.
