The choice. expansion joints at close intervals with increase of maintenance cost. It is only economic for spans less than 30 m. Due to presence of large girders and its arrangement, it has less clean appearance. The research was performed to develop guidelines for design and construction and to address issues that significantly influence performance. To find out the methodology to be followed, The paper presents a meta-design approach to the design and development of interactive systems, which bridges the communication The, if any, and the formation level of the embank. A three-span bridge having a span configuration of 190-240-190 ft is considered for both examples. Hence, Pigeaud's method is most appropriate for the design of deck slab. = Basin area below 3000 m elevation in square kilometers, = 6.8 for areas within 80 km from the east coast, =Dickens constant with the value of 6 to 30, = a constant which varies from 0.18 to 1.88, Spread Footing (Isolated footing, combined footing, strip footing), Movement of the girders in the longitudinal direction due to variations, The deflection of the girder causes rotations at the supports, Due to sinking of the supports the vertical movements are developed, Movements due to shrinkage and creep of concrete, In the case of prestressed girders, prestressing the girders cause movements of girders. Loading – Single lane of Class 70-R or two lanes of Class A: Let the cross-section of the deck be assumed as shown in Fig. structure and raft approximately to weight of soil excavated. Design Example Provided by Er. This bridge was launched in two trains, one from each side of the river.

The design example and commentary are intended to serve as a guide to aid bridge design engineers with the implementation 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 recommended by IRC forms the base of our design. Our height of abutment is above 6 m and hence, reinforced concrete abutment is preferred. A girder bridge is very likely the most commonly built and utilized bridge in the world. Effect of wind loads acting on the moving vehicles and the superstructure. IRC:6-2016, Standard Specification and Code of Practice for Road Bridges, Section IILoad, 4.
