Review of Design Procedure for Box Girder Bridges

Abstract

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 With rapid technology growth the conventional bridge has been replaced by innovative cost effective structural system such as T-Beam Girder System and Box Girder Bridge System.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...

Vibration analysis of crack developed bridge using ANSYS

“…The bridge superstructure of prestressed concrete girder bridges has been analysed parametrically [1]. Pragya Soni, [2017], The act of bridging predates the development of human civilisation. Since the beginning of time, many bridges of all shapes and materials have been constructed.…”

“…Accounting for the span, the cross section of the superstructure, the price of the prestressing steel, and the amount of concrete used may all help to achieve economy. In the present study's parametric analysis, the superstructure of the prestressed concrete girder bridge is taken into account [10]. Jagdish Chand, Ravikant Flybys & bridges are often built using T-beam and box type sections.…”

Flexural Behavior of Concrete Box Girders Reinforced with Mixed Steel and Basalt Fiber-Reinforced Polymer Bars

“…Box girder Bridges nowadays has achieved a prominently usage in the construction industry. It gained this popularity due to its accelerated construction, high flexural and torsional stiffness, serviceability, favorable depth-to-weight ratio, aesthetic shape, and economical-effectiveness [1][2][3][4][5][6]. As a member of reinforced concrete (RC) bridges, RC box (RCB) girders are directly exposed to the air and sometimes to the detrimental gasses from the ecological contaminants.…”
