Abstract
In this paper, an improved concrete constitutive model based on bounding surface model is presented, Many ldnds of load cases are treated by means of this model, The theoretical calculation results agree with the available test data,indicating that the improved model is more acctale and effective, The present model can be used in the finitc element analysis.
