Abstract-Due to population growth and rapid urbanization, there has been an enormous growth in traffic volume on highways over the last few decades. In order to ensure smooth flow of traffic, numerous new highways and flyovers are being constructed. The use of box-girders has proven to be a very efficient structural solution for highway bridges and flyovers due to its high tensional rigidity, serviceability, economy, aesthetics and the ability to efficiently distribute the eccentric vehicular live load among the webs of the box-girder. For the multi-lane bridges, multi-spine/cell box-girders are most commonly adopted in order to limit the local deformations in the top slab of box. Many studies are available on suitability of box girder bridges for various spans and effect of stresses for skewed box girder bridge. The curvilinear nature of box girder bridges along with their complex deformation patterns and stress fields have led designersto adopt approximate and conservative methods for their analyses and design. Recent literature on straight and curved box girder bridgeshas dealt with analytical formulations to better understand the behavior of these complex structural systems.It was found that researchers have used finite element method for the analysis of box girder bridge. However, not much studies are available for the design of box girder bridge.Hence, this study emphasized on the design and analysis of box girder structure.The literature also indicates that the various researchers have used ANSYS, MIDAS and Stadd-Pro for the analysis of Pre-stressed Concrete Structures using FEM. Keywords-Box girder, Torsional rigidity I.INTRODUCTION Bridge is life line of road network, both in urban and rural areas. With rapid technology growth the conventional bridge has been replaced by innovative cost effective structural system such as T-Beam Girder System and Box Girder Bridge System. In spite of difficult design procedure and complex form work requirement , box girders, have gained wide acceptance in freeway and bridge systems due to their structural efficiency, better stability, serviceability, economy of construction and aestheticappearance.In bridge design procedure span length and live load are important and affect the conceptualization stage of design. Various live loads that are defined by IRC 6:2016 and experienced by bridge deck system are Class A, Class B, Class AA and Class 70R. These are the combinations of wheel load and track loads. Wheel loads are one which are transferred by the wheels of trucks and track loads are one which are transferred by pair of wheels and axels connected by belts. The effect of these loadsvaries from span to span. For example, on shorterspans track load governs whereas on larger span wheel load govern. Designs considering combinations of these loads on bridge deck system provide scope for research. However, the bridge deck structural system adopted is influence by factor like economy and complexity in construction. This paper undertakes the review of published records on all s...
Pre-stressed concrete is the type of concrete in which internal stresses of a suitable magnitude and distribution are induced so that the stresses resulting from external loads are counteracted to a desired degree. Pre-stressed concrete structures exhibit high strength and durability. These types of structures are very popular in use in bridge deck systems and culverts. However, various elements of pre-stressed concrete member undergo different types of stresses. The weakest element of these being beam column joint. The beam column joint in pre-stressed concrete member undergoes direct compression as well as bending compression and tension. This peculiarity of the beam column joint makes it vulnerable to failure. It was found that many authors studied the analysis of pre-stressed concrete structures using Finite Element Analysis. However, they have not included the beam column joint in their analysis. Hence, this study emphasized on this aspect of analysis of prestressed concrete structures. This paper presents the review of literature on 'Analysis of Beam Column Joint of a Pre-stressed Concrete Structure Using Finite Element Analysis'. It is been also observed from the existing literatures that Finite Element Method (FEM) is widely used for analysis of Pre-stressed Concrete Structures. The FEM is capable of incorporating complex boundary conditions and material non-linearity. The results of FEM are also comparable with that of hand calculations. Also the structure can be finely idealized using FEM which enhances accuracy of analysis. This will economize the structural sizes of Pre-stressed Concrete Element. The literature also indicates that the various researchers have used ANSYS, MIDAS and Stadd-Pro for the analysis of Prestressed Concrete Structures using FEM. This was an important observation and hence the present study aims to use ANSYS for the analysis of Beam Column joint using FEM. The present study aims at reviewing various research efforts undertaken by authors in the past. The study also aims at finding a gap in literature on analysis of beam column joint in a pre-stressed concrete member using Finite Element Analysis.
