Precast concrete box culvert will be used in this design tutorial. It is typically used for conveying water and also frequently used for pedestrian or cattle underpasses. Currently, most box culvert installations are provided in precast form due to the huge reduction of time for place production and construction. Embankments are used to balance the flood water on both sides. Box takes various types of loads generated by water, traffic, cushion, soil etc. This work deals with complete design of box culvert manually and study the design parameters such as effect of earth pressure, depth of cushion at the top slab of culvert, factor such as braking force, Impact load, Live load, Dispersal of loadIn this work, study of culvert with and without cushion analyzed for different classes of IRC loadings and conclusions made on the basis of Bending moments and shear forces with and without cushioning cases. This paper provides full discussion of provisions provided by Indian Standards, their justifications and considerations are taken into the account for design purpose.

One of the solutions adopted as per analysis is that there should be opening criteria of shear wall within the limit. This will be a most effective solution of cost reduction of the building along with the seismic resistant structure. In this work, firstly literature survey has performed and it has been seen that most of the researchers done a very good job to make the seismic resistant building. On other hand, none of them have done the opening area effect of the shear wall to make it cost effective. The following work started with the introductory part with types of core type shear wall then types of wall opening. After then review of literature have been performed then at the end of the work, conclusions and outline of the proposed work have made.

To provide stability to tall structures when shear wall is not enough to provide lateral support, therefore wall belt supported system is the one of the best technique to increase the stability of the same. Wall belt supported system is provided at the periphery of the tall structures throughout its height to increase the stability. The current work shows the literature survey of various researchers who have been contributing in this field. Conclusions with the outline of the proposed work are provided at the end of the work.

To make economic structure without losing the stiffness criteria, the work has been performed in two stages. The former one is building with single shear wall core and the latter one is building with dual core shear wall; the entire work has performed with four different phases. In first phase total 5 buildings that are modeled with different openings in single core types shear wall and then second phase performs the analysis procedures of the same. The third phases have total 6 buildings that are modeled with different openings in dual core types shear wall and then fourth phase performs the analysis procedures of the same. The result analysis has been performed and then conclusions are drawn. Building with 25 opening area in single core type shear wall and 50 opening area in dual core type shear wall performs well to reduce the cost of the project.

View Show abstract Analysis and Design of RCC Box Culvert Article Dec 2014 Neha Kolate Molly Mathew Snehal Mali Culverts are required to be provided under earth embankment for crossing of water course like streams, Nallas etc.The culverts are also required to balance the flood water on both sides of earth embankment to reduce the flood level on one side of road thereby decreasing the water head consequently reducing the flood menace. This paper deals with study of some of the design parameters of box culverts like angle of dispersion or effective width of live load, effect of earth pressure and depth of cushion provided on top slab of box culverts. Depth of cushion, coefficient of earth pressure for lateral pressures on walls, width or angle of dispersion for live loads on box without cushion and with cushion for structural deformations are important items. Keywords: angle of dispersion, box culvert, coefficient of earth pressure, cushion, lateral earth pressure etc. View Show abstract A STUDY OF BEHAVIOR OF RCC BOX CULVERT UNDER THE INFLUENCE OF STATIC AND DYNAMIC LOADS IN ACCORDANCE WITH IRC Article Oct 2017 Mahesh D Kakade Rajkuwar A Dubal Box culvert problem is a complicated example of soil structure interaction where the relative stiffness between the backfill soil and the culvert materials is critical factor in the load carrying capacity of culverts. Culvert is provided under earth embankment for crossing of water course like streams. across the embankment, as road embankment cannot be allowed to obstruct the natural water way This project deals with study of some of the design parameters of box culverts like effect of earth pressure and depth of cushion provided on top slab of box culverts and the relative study of box full and box empty conditions is done using finite element analysis tool ANSYS.

View full-text Article Full-text available Analysis and Design of Box Culvert: A Review April 2019 Sagar Jamle Roshan Patel Box culverts are the structures which are used when the path of water in the natural stream crosses roads, railway lines, flyovers etc. They are normally cheaper than bridges, which make them the natural stream passes through channels. The IS standard requirements in the design manual for roads and bridges (IRC-6-2000, IS 21-2000) is used in the structural designing of concrete box culverts. In this paper study about the different classes of IRC loadings and their effect on without and with cushioning conditions imposed on box culvert.

The pressure cases are then checked for both with cushioning and without cushioning loading cases. The structure designing includes the considerations of pressure cases (Box empty, Full, surcharge load) and factors such as Impact load, Braking force, Dispersal of load through fill, Effective width, Coefficients of earth pressure, Live load etc. The structural elements are designed to withstand the maximum bending moments and shear forces respectively. In the present study, this paper provides full discussion on the provisions in the codes, considerations and justifications of all the above aspects of design. Therefore, this research focuses on the impact of using haunches on the economy of the culvert design. This paper studies some design parameters of box culverts, such as the thickness of the haunch, the coefficient of earth pressure, the thickness of box culvert, and depth of fill on the top slab. The objectives show the effect of haunch on the stresses of the box culvert. The study investigated the variation in stresses and the cost comparison made for different width of the box culvert. The percentage reduction in the cost of culvert based on the presence of haunch is presented. At last, several significant conclusions are given based on numerical results as the presence of haunch is the best solution for decreasing the values of stresses from the economic point of view. View full-text Preprint Effect of Haunch on the Stresses of Box Culvert August 2019 Osama Hussien Culverts are often required under earth embankment to allow for the crossing of a watercourse, like streams, to prevent the road embankment from obstructing the natural waterway. The opening of the culvert is determined based on the waterway required to accommodate the design flood, whereas the thickness of the culvert section is designed based on the loads applied to the culvert. The study investigated the variation in stresses and the cost comparison made for different width of the box culvert.

The center of mass is determined from mass d istribution of the attached shapes or is explicitly set with b2 MassData. Much of Box2D's internal computations use the center of mass position. For example b2Body sto res the linear velocity for th e center of mass. When you are building the bod y definition, you may not k now where the center o f mass is loc ated. Therefore you specify t he position o f th e body's origin. Yo u may also spec ify the body's angle in radians, which is no t affect ed by the position of the center of mass. A rigid bod y is also a frame o f reference. Yo u can define fixtures and joints in that frame. Tho se fixtures and joint anchors never move in the local frame of th e body. Damping Damping is used t o reduc e the wor ld velocity of bodies. Dampi ng is diff erent t han friction because friction o nly occu rs with contact. D amping is not a replacement for frict ion and the two effect s should be used together. T his is not an issue if you u se a fixed time step (reco mmended). Gravity Scale You can use the gravi ty sc ale to ad jus t the gravi ty on a single body. Well it is expens ive to simulate bo dies, so t he less we have to simulate t he better. When a body comes to rest we would like to stop simulating it. When Box2 D determines th at a body (o r group of bodies) has co me to rest, the body enters a sle ep state which has very li tt le CPU overhead. If a bod y is awake and c ollides with a sleep ing body, t hen the sleeping bod y wakes up. Bodies wi ll also wake u p if a joint or cont act attached to them is dest royed. You can also wake a bod y manually. Such a body should n ot r otate, even under load.
