In this paper, the method of model established on reinforced concrete pier based on OpenSees was studied, and the parameter sensitivity analysis to OpenSees was carried out according to the test data. On the basis of introducing the related material model and element type, how to determine material model and element division as well as section meshing were studied, and the method of model established both reasonable and effective was given. The model of concrete material which can improve the convergence of calculation and the model of reinforced materials which can simulate elastic and reinforced plastic stage accurately were given in this paper. The results show that the distributed plastic beam-column element based on displacement can get higher calculation precision. At the same time, the bridge pier structure should be meshed sufficient number of elements and girds to meet the requirement of calculated accuracy.
