Abstract: By means of different steel and concrete uniaxial constitutive models, a comparative research of the elastic-plastic dynamic analysis of reinforced concrete frame structure subjected to earthquake is camed out. On the basis of fiber beam element modelin ABAQUS, different steel and concrete uniaxial constitutive models are used in the dynamic elastic-plastic time history analysis of an overrun reinforced concrete frame structure under rare earthquake. The analysis results from different material models are compared with each other in detail. The results demonstrate that the time history dynamic response of structure has little difference, even if the steel and concrete uniaxial constitutive models are different. There is no significant influence on results of the time history dynamic response due to the choice of uniaxial constitutive models of steel and concrete. The uniaxial constitutive model of concrete named Concrete02 and of steel named Stee102 in Opensees are combined can obtain the highest computational speed.
Keywords: rare earthquake; elastic-plastic dynamic analysis; fiber beam element model; uniaxial constitutive models of material
