STUDY ON BENDING STRENGTH AND EVALUATION OF BOLT AXIAL FORCE FOR THE DOUBLE END PLATE CONNECTION WITH HORIZONTAL RIBS

Abstract

In this study, for shortening erection period of temporary bridges, we propose to use the double end plate connection using high strength bolts at the connection of temporary bridges. The past experiment has confirmed that double end plate connection using high strength bolts can apply to bridge main girder connection. However, the design method is not clear. In this study, we have clarified the bending strength of this connection from the analytical results. Furthermore, in consideration of these results, a simplified calculation method of bolt axial force for this type connection proposed.
