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. Steep slopes result in shorter time of concentrat, Where, Q =maximum flood discharge in m^3 per second, Io =peak intensity of rainfall in mm per hour, λ = a function depending on the characteristics of the, L = distance from the critical point to the bridge site in kilometers, H = difference in elevation between the critical point and bridge site in kilometers, n = manning's coefficient calculated from table, two cross sections over a long distance.

The Talmadge Bridge, Savannah, Figure 19.5, is 1.45 m deep for a 335 m span, The ALRT Skytrain Bridge, Vancouver, Figure 19.6, is 1.1 m deep for a 340 m span and the design of the Portsmouth Bridge had a 84-cm-deep girder for a span of 286 m. Because the girder is very flexible, questions concerning buckling stability occasionally arose at Height: Height is kept equal to that of piers. 2. 5. To meet the need for use of such structural elements, design criteria had to be established. The bridge design was performed according to the Canadian Highway Bridge Design Code (Almansour and Lounis, 2008). prestressed concrete girder bridges shall be estimated using the provisions of Section 5.1.1. design as the bridge design receives heavy patch load.

Design requirements for the Network Rail Standard Box Girder bridge are given in documents available from Network Rail. Abutment should be designed in such a way that it can resist the forces mentioned above. In modern girder steel bridges, the two most common shapes are plate girders and box-girders. Concrete Box Girder Bridges J. Schlaich Scribd. The various forces to be considered in the design of piers are as follows: 2. highways and streams not perpendicular to the bridge alignment • Allow for reduced girder span lengths and bridge deck area, as well as reduced girder depths • Increased torsion in the girders, larger than normal cross-frame forces, unique thermal movements, … The guidance in this publication has been developed from earlier well-established guidance in a number of SCI bridge design guides. These reduce the possibility of accidents due to head on collisions.
