| Abstract: | Creep of concrete remarkably affects deformation and internal force of simply supported and structure continuous beam bridges and should not be ignored in design and construction. This paper performs theoretical calculation for creep of simply supported and structure continuous beam bridges, and analyzes the laws of influences of concrete creep on internal stress and deformation of structure by means of application of examples. |
