ARCH BRIDGE AT DODAN NALLAH

The design and construction of the arch bridge at Dodan Nallah, India, are described. This project shows how innovative structural design and analytical techniques, combined with meticulous planning and the use of appropriate construction methodologies, can reduce costs and consumption of materials, without harming maintenance-free characteristics, quality control, durability, and aesthetics. The structure's aesthetic appearance was carefully designed, so that it would enhance the magnificence of the bridge's natural surroundings. The bridge has a 7.5m wide two-lane carriageway with no footpaths. Its arch has a 40m span and 20m high embankments. The structure was made monolithic, to eliminate expansion joints and bearings. Seismic loading was considered for static effects of 0.12g. The arch rib was constructed in in-situ concrete after the complete centring was erected. The time taken for the major concrete pours was: (1) 60h for foundation (quarter segment); (2) 72h for arch rib; and (3) 60h for deck slab. The bridge is beautiful and durable, and was easily constructed, due to its design conception using simple forms.
