A three-span bridge having a span configuration of 190-240-190 ft is considered for both examples. SUPERSTRUCTURE DESIGN 1.1 RC DECK OF RC GIRDER BRIDGES The design example comprises of 5.35m wide deck with 2-girder arrangement. The earth face is provided with a batter of 1 in 3 to, Abutment width: The top width should provide enough space for bridge, bearings and bottom width is dimensioned as 0.4 to 0.5 times the height, Length of abutment: The length of abutment must be at least equal to, Abutment cap: The bed block over the abutment is similar to the pier, Longitudinal force due to tractive effort and braking, The ratio of span to the width of bridge greater than 2 but less than 4. 10. When the above practical method is not possible, the normal depth of scour may, by equation for natural streams in alluvial beds. Our height of abutment is above 6 m and hence, reinforced concrete abutment is preferred.

The two most common types of modern steel girder bridges are plate and box. This type with cut ease water is widely used for river bridges. Therefore, the purpose of this paper is to present information relative to the design criteria in addition to information on pre­ liminary plate sizes, design aids, and computer-aided design of steel box girder bridges. Further, they are used to develop the box type girders. Solid Slab Bridge Design • Box-Girder Bridge Design 9.1 Introduction The raw materials of concrete, consisting of water, fine aggregate, coarse aggregate, and cement, can be found in most areas of the world and can be mixed to form a variety of structural shapes.

Longitudinal forces due to resistance in bearings. This bridge was launched in two trains, one from each side of the river. Based on these, the summation of load effects due to different load combinations for various load factors are obtained. ResearchGate has not been able to resolve any citations for this publication. If the railway track is near. Mainly there a prestressed concrete girder bridges shall be estimated using the provisions of Section 5.1.1. bunds at that point, for high level bridges, the freeboard should not be less than 600 mm.

Hence, Pigeaud's method is most appropriate for the design of deck slab. This article discusses the general design considerations, design sequence, conceptual and detailed design requirements, and analysis procedures of segmental prestressed concrete box girder bridges. Height: Height is kept equal to that of piers.
