The Third Karnaphuli Bridge spanning the Karnaphuli River in Bangladesh is a significant new landmark in the port city of Chittagong. Designed to withstand earthquakes, the 950-meter crossing consists of three 200-meter extra-dosed main river spans, two 115-meter side spans, and a 120-meter approach viaduct with 20-meter spans. The design-build contract stipulated that the main bridge structure have the extra-dosed, concrete cable-supported deck—a state-of-the-art building technique pioneered in South East Asia and Japan.
High-Point Rendel used RM Bridge for static and dynamic global analysis, and simulation of the complete structure including foundation stiffness, piers, and deck for all stages of construction. The $80 million project’s on-time, on-budget completion was due in part to having a viable tender design concept that changed very little during construction.
