| Abstract: | Steel-concrete composite box-beam is a new type of steel-concrete composite structure and has certain advantages in bridge reinforcement and reconstruction. Taking a pedestrian bridge as example, we designed a composite box-beam based on lengthening reinforcement scheme which useed steel plate-concrete composite bridge decks as shear connectors and made an analysis with finite element method. The result shows that the composite box-beam scheme with steel plate-concrete composite bridge decks is a simple and effective method for pedestrian bridge, which can improve the stiffness of the structure to meet the requirements. |
