| Abstract: | According to the age adjusted effective modulus method, a computing program for the analysis of segmental built continuous beam bridges considering time dependent effects of creep and shrinkage of concrete is presented in the paper. The calculation example shows that correct estimation of creep deformation is important for building control. |
