| Abstract: |
Nivedita Setu is the state-of-the-art, multi-span extradosed cable stayed bridge supported by single plane of cables. This landmark six lane road bridge deck is 29m wide single cell precast concrete segmental box. The pier table supported on a single pylon pier was a critical part of the superstructure. Huge dimensions and massive weight of pier head and integrated with the pylon pier posed a major challenge to bridge engineers. An innovative state-of-the-art solution of steel- concrete composite structure was developed to simplify the construction in terms of both time and cost. The significance of hybrid steel stability frame-precast shell amalgamated into the optimum choice of handling and transportation of segments to bridge site without exceeding the capacity of construction machinery and erection tackles. The paper discusses the innovative technique in design and construction of the critical pier head segment and its impact on completion of the iconic bridge. |
