摘要：

In order to analysis of concrete based on ABAQUS, A creep and shrinkage of concrete analysis program TDPA was developed. Firstly, the theory of creep and shrinkage effect of concrete was introduced, with the help of a Dirichlet series properties, creep stepwise recursive method was introduced to avoid stress history of large capacity storage; Secondly, using three user subroutine interface USDFLD, GETVRM, UEXPAN provided by ABAQUS, analysis program TDPA was developed by Fortran program language; Finally, typical long-term load tests of pre-stressed concrete and steel concrete composite members long term tests were selected to prove the reliability of TDPA. Research results show that: the TDAP has high applicability and reliability. It is suitable for a variety of creep and shrinkage prediction model, and provides an effective method for creep and shrinkage of concrete analysis on ABAQUS platform.
