AbstractA new nonlinear viscoplastic body considering cohesion and internal friction coefficient versus time is proposed by considering cohesion and internal friction angle. A new creep model for concrete considering cohesion and internal friction angle is obtained by interlocking it with the conventional model. The results show that the creep model can properly reflect the creep development of soft‐cut concrete at the pile head by comparing the creep model with the three‐dimensional creep test data trends under various levels of loading. The model can well describe the whole process of creep deformation and also better compensate for the shortcomings of the traditional creep model that cannot describe the characteristics of accelerated creep deformation.
