Behavior study of precast pier of bridge for its various shape

Abstract

This study presents the analysis and design of precast pier as per Indian standard codes. The analysis and design of pier is carried out by considering various loads as per Indian standers and IRC codes. The design of precast pier is carried out using the STAAD. Pro software. To study the effect of water pressure on precast pier various shapes of pier are considered like rectangular, circular, pier with triangular cut, pier with arch. The comparison of dis-placement, stresses, strength, and stiffness of different shapes are analysed to evaluate the behaviour of pier. The design of connection of the precast pier is done using IRC codal provisions. Looking to the results precast pier with circular shape is most suitable shape than other considered shape by having more stiffness in each direction, but to resist stresses the rectangle shaped with arc is good choice. And the displacement of pier having rectangular shape is less compared to circular pier.
