Construction of Long-span Doubly Curved Arches for a Pedestrian Bridge
We supervised the construction of two doubly curved variable depth reinforced concrete arches of a pedestrian bridge each having a span of 71.3m and fabrication of the deck system as well. The pedestrian bridge was Constructed over the Crescent Lake near the National Parliament Building in Dhaka, Bangladesh. The bridge facilitates the movement of pedestrians to the nearby mausoleum of Shaheed Ziaur Rahman, former president of Bangladesh and the adjacent Chandrima Garden. The bridge having a suspended span of 56.1m allows the movement of pedestrians over a steel framed tempered glass deck, the first of its kind constructed in Bangladesh. The construction process for the arches included the use of pumped fair faced concrete. Steel shutters for the doubly curved arches were produced by using CAD generated shop drawings. The bridge was opened for public in 2004.
