“…The study of wheel load is required to revise. Shear Behaviour and Mode of Failure experiment done by Ali Abolmaali and Anil K. Garg on Reinforced Concrete Box Culverts in 2009 for ASTM C1433Precast.In this paper comprehensive experimental and numerical study was undertaken to research the shear behaviour of box culverts for standard sizes as per ASTM C1433 [5][6][7][8]. The failure of section due to shear is investigated under the influence of different variables, including culvert size and capacity and the location of the load.…”

In the present scenario, Minor bridges over small rivers have become necessary for the nation’s development to connect the country’s most remote corners. In this paper initially, 30 m of Minor Multi-cell Box type Bridge with different number of precast sections along with the different types of load such as Dead Load, Live Load, Super Imposed Dead Load, Earth pressure, and vehicle load such as Class “A” vehicle, 70R bogie vehicle, 70R Wheeled vehicle, 70R Tracked vehicle, as per IRC is analyzed. Also, various Load Combinations are applied to bridge structure such as limit state of collapse and limit state of serviceability, for accurate results of Bending Moment and Shear Force critical sections are marked. The aim and objective of the work are to analyze and design the different span lengths 3.43, 4, 4.8,6,8 m of box sections for the Indian Road Congress Code (i.e. IRC 6-2017 and IRC 112-2011). This has been done by analyzing the structure using software STADD PRO V8i. And design validating with manual results by developing the Microsoft Excel Sheet. From analysis and discussion, it is concluded that 5 sections of 4.8 m span which give better results and minimum cost compared to other section.

“…Software like SAP and ABAQUS have already been implemented for the analysis of box culvert for wheel load and other complex real life loads. It has been seen that the solution to such loads are not easy and sometimes impossible by the means of conventional methods [11,13]. FEM can be applied where the loads are dynamic in nature or where the varying loads are experienced [8].…”

There are several researches already have been done on behavior of reinforced concrete (RC) box culverts in past with different conditions of loads. The design and analysis of box culverts is a complex task. The present era offers the finite element analysis of 3D model of structures, making it easier through software. The conventional methods have been used extensively for design but the use of finite element method (FEM) has not been so popular yet. Finite element analysis of box culvert for parametric studies has been carried out, even for different aspect ratio. Here an effort has been made to show the economic and effective design can be achieved by doing finite element analysis of a box culvert whose concept can be used for large structural design as well. This paper shows the comparative study of analysis of conventional method using STAAD software and of FEM using ANSYS software. A box culvert is a structure consisting two parallel slabs monolithically connected to its vertical slabs allowing an opening for waterways and other ways. The box culverts are ideally suited for the low stream water bodies, railways crossing of high embankments, for road crossing of low or medium traffic density and for the sites where bearing capacity of soil is low. The overall dimension of a box culvert is kept within 4m x 4m due to the fact of synergy deflection [4]. If only one box is implied for the purpose, it is called 'single celled box culvert' and if the purpose requires culvert of more than one box, it is called 'multi-celled box culvert'. A box culvert has many design and installation advantages. One such is that it does not need a separate foundation to be laid on. The bottom slab serves as a raft foundation hence minimizing the pressure on soil. The culvert experiences an up-thrust force from soil which has also been considered in the paper. There are several types of loads acting on a box culvert such as self weight of the culvert, live load on top slab in the form of moving wheel load, earth pressure acting from outside, water and air pressure acting from inside and upward soil thrust on the bottom slab. Hence critical analysis of culvert is necessary to ensure the best service. Box culvert while designing should also follow certain aspect ratio as it is important to obtain an optimum thickness of the slab. Kalyanshetti M. G and Gosavi S [5] have shown in their research that for a certain lengths of the culvert, there are different aspect ratios for obtaining economical design of box culvert. Dynamic effect of moving truck has also been discussed by Chen S. S and Harik I. E in which a time dependent variable dynamic system is solved step by step. Calculations have been made considering parameters like truck velocity, surface roughness, damping ratio, truck culvert frequency ratio and road material. [8] The results found in the paper are uneconomic. Hence this paper can also find the way to make the design of dynamic effects on culvert more economic. Kumar Y. V. and Dr Srinivas C [2] has done a computational anal...

“…The importance of the load distribution on the buried structures still an important research topic. Either using classical or alternative filling materials, researchers have been studied the accurate load distribution methods of these materials [1][2][3][4][5][6][7][8][9] with others. These studies showed that the correct live load distribution is an important parameter in FE modelling either using traditional or any material as filler material.…”

The buried culverts have been in service more than half a century and the age of them raise question about their reliable serviceability for the new standard vehicles. The gross weight and axle spacing of these trucks play an important role on the performance of the buried culverts where the culvert covered with shallow fill heights. Field live load tests were conducted by driving a loaded truck over some culverts at slow speed while recording data at the critical locations of these culvert. Finite element (FE) models were developed and calibrated using field load test results. Live load distribution formulations were adopted from AASHTO LRFD Bridge Design Specifications for different fill heights. Two-and threedimensional FE models were modeled and loaded separately to compare the critical section forces. The results showed that the error using two different FE modelling approach yields more than 100% error for the maximum section forces when fill heights is between 60 cm and 120 cm. This study aimed to highlight the inherent error in numerical modeling of the buried reinforced box culverts for design or rating purposes.
