STUDIES ON MAJOR ELEMENTS OF AN ELEVATED METRO BRIDGE

STRUCTURE ENGINEERING

This Research paper is limited to study of two two major elements.of metro bridge , pier and box girder .In the first part of this study, the performance assessment on designed pier by Force Based Design and Direct Displacement Based Design is carried out. The design of the pier is done by both force based design method and direct displacement based design method.In the second part, parametric study on behavior of box girder bridges is carried out by using finite element method. The numerical analysis of finite element model is validated with model of Gupta The parameter considered to present the behavior of Single Cell Box Girder, Double Cell Box Girder and Triple Cell Box Girder bridges are radius of curvature, span length and span length to the radius of curvature ratio. These parameters are used to evaluate the response parameter of box girder bridges namely longitudinal stresses at the top and bottom,shear, torsion, moment, deflection and fundamental frequency of three types of box girder bridges.
