【Abstract】 According to the characters of reinforced concrete girder bridges, this paper gives the decreasing rates of bearing capacity of basic members in each segment, and integrates the decreasing rates into evaluation index of the structural system based on the theory of analysis, then it creates a useful evaluation method for bridge structural system, and on this basis an automatic evaluation system can be developed.更多还原
