Study on Effect of Joints in Segmental Concrete Bridges

Author : Mathew C S 1 R K Ingle 2

Date of Publication :24th January 2018

Abstract: The segment of joints is the locations of primary concern in the analysis and design of segmental concrete bridges. Joints are responsible for the transfer of bending moments and shear forces developed in one segment to the other. Hence in the majority of the cases, the capacity of the joints becomes the governing factor than the capacity of the segments. The capacity of joints depends upon the level of fixity between the segments. It is practically impossible to provide a fully fixed joint between the segments. Hence in this paper, the efficiency of joints with varying levels of fixity has been studied and is then compared with a geometrically similar continuous box girder bridge. It has been observed that efficiency of joints directly depends upon the level of fixity between the segments.
