- Abstract
Nowadays all the existed prediction models around the world are only suitable for ordinary concrete with a strength lower than C40 or lightweight aggregate concrete with a strength under C30, however, there exists no prediction model for high strength concrete structures. Through the analysis and comparison of each creep prediction model, this paper concludes with reference to the proposed model of Japanese Concrete Codes. On the basis of creep test of high strength concrete, a creep prediction model for high strength concrete is proposed.Based on Abaqus Scriping Interface, new user's material properties that fitted Modified Model were created by Python. By comparing results of calculation and test data, a rule of creep's progress was obtained.
