【Abstract】 The calculation methods of ductility rate of frame member in the design of elevated railway bridges in Japan are introduced. The calculation results of ductility of frame member and structure are important parameters which influence the evaluation of quakeproof structure in the design of ductile and quake proof structures. Many elevated railway bridges employ monolayer or multilayer rigid frames, and the reasonable evaluation of the frame is an important subject in quakeproof design of railway bridges.更多还原
