This article takes the Songhua river bridge as the engineering background. Bases on the existing seismic non-linear theory, the author study that the bending moment-curv-ature hysteretic characteristic curve can use the Takeda (Tak-eda) three linear models and gives the elastic-plastic time history response analysis under the 8 degrees area under severe earthquake, and evaluates the aseismic ability under severe earthquake.
