| Abstract: | Creep effect has been seldom taken into account on design and construction of small and medium-sized span concrete girder bridges in engineering field.Finite element analysis which involves concrete creep effect is built for Tangwan Bridge based on calculation theory and method of concrete creep effect in this paper.Some significant conclusions are got here and it is also a reference for the engineers. |
