Aiming at the problem of creeping effect of concrete structure, the age -adjusted effective modulus method is combined with the ANSYS finite element commercial software package to introduce the "unit life and death" technology into the creep analysis of the concrete structure segment construction process. The data trans- mission problem between the segment construction process, and based on the ANSYS parametric design language APDL, the command flow is compiled, and the creep effect analysis problem is transformed into pseudo-elastic analysis problem, and the calculation is simple. Taking the classic three-section continuous beam bridge as an example, the creeping coefficient calculation formula of the current code "Code for Design of Highway Rein- forced Concrete and Prestressed Concrete Bridge and Culverts" is used to analyze the creep of the continuous beam bridge. The internal force is compared with the existing calculation results, which proves the feasibility and effectiveness of the proposed method. And the node displacement curve of each node is drawn.
