摘　　要：This paper summarizes suitable material models for creep and damage of concrete which are coupled with heat and moisture transfer.The fully coupled approach or the staggered coupling is assumed.Governing equations are spatially discretized by the finite element method and the temporal discretization is done by the generalized trapezoidal method.Systems of non-linear algebraic equations are solved by the Newton method.Development of an efficient and extensible computer code based on the C++programming language is described.Finally,successful analyses of two real engineering problems are described.
