and railway transportation system, generally serving as social infrastructure system. The main objective of this study is to match the structural members capability between the differing types of piers with U- beam girder under gravity, seismic and vehicle loading. This study investigates efficiency of piers with U- beam as girder on seismic as well as structural analysis and design of integral bridges by using finite element analysis software ANSYS 16.0 version. The structure of the bridge will be design in CAD model software called CREO PARAMETRIC. The investigation mainly analyzes the structural member capability between girder shape (U- beam) and piers (hammer head pier, multi column bent, solid wall type pier) by applying different loading conditions.
The bridging activity is as old as human civilization. Innumerable bridges of various kinds and of various materials have been built from times immemorial. Design of medium span highway bridge system requires careful selection of structural element in preliminary stage. The motive behind the study is to prepare some useful interface for preliminary design of bridge system. There is no unique form of design which would be always most economical. It is only by comparing a few designs that the economic design can be found in a particular set of conditions. Economy can be achieved by separately or simultaneously considering one or more of the following factors: span, superstructure cross section, cost of prestressing steel and concrete consumption. The study includes parametric study on prestressed concrete girder bridge superstructure. [3]

1. INTRODUCTION Bridges structures are momentous and proficient civil structures and they contains on different types of structural members. These members can be divided into two groups. The first group is called superstructure and it includes the bearings, girders (beams), deck (including sidewalks), joints, asphalt pavement layer, security barrier, and drainage system. The second group is known as substructure which is contained on the foundations (piles and piles cap), piers, and pier caps. In general, bridges are important part of the transportation engineering system. It presents the connection way over urban congestion, waterways, and valleys. The bearing capacity of bridges controls the weight and the volume of traffic loads which are passed by the transportation system.
1.1 Objectives
This study deploys simulation of nonlinear analysis of bridge using DRAIN 2DX. Paper presents details seismic analysis of RC multicolumn bridge bents and four seismic [2]

Impact Factor value: 7.529
To determine deformation, stress, ultimate load and moment of U- beam girder with piers such as hammer head, multi column bend and solid wall type piers under loading conditions (gravity, seismic and moving loads).
To validate and check the possibilities of finite element programming using ANSYS software for bridge analysis.
1.2 Scope of the Project Work
The objective of the study is to compare the structural members capacity between different types of bridges structures under seismic load using CSI bridge. Bridges structures models are box girder bridge, solid girder bridge model, Precast I girder bridge, Slab bridge, Precast T girder bridge, U steel girder bridge. The result showed that models of box girder, precast T, and U steel girder bridge had the higher values of natural frequency comparing with other structures [1]
