Paper Title
Effect of Change in Radius of Curvature in Plan on Bridge Bearing Reactions

Abstract
Bearing is very small part of bridge compared to all other components. Though it is small part requires more attention as entire load is transmitted from super-structure to sub-structure through bearings. Bearing not only helps to transfer the force of super-structure to sub-structure but also resist or transfer the deformations of super-structure with respect to sub-structure which were unavoidable in case of high altitude and large span bridges. This study includes effect of geometry of a bridge on selection of bearing. To demonstrate effect of geometry on variation in reactions combination of simply supported spans and curved spans with and without curvature in plan where considered. Keywords— Bearing, Super-Structure, Sub-Structure.
