| Abstract: |
The New Storstrøm Bridge in Denmark has 40 concrete piers ranging from 18 to 35m high. The piers comprise multi-faceted stems and pier heads. To simplify offshore construction a precast segmental solution was used, with a prestressed insitu pier head. The design was optimised through parametric analysis including non-linear modelling and automated calculation reporting. A modular approach maximised repetition of segments between different pier heights to enable precast construction in a factory environment prior to assembly offshore. Non-linear dynamic modelling was used to validate resistance to ship impact. Detailed analysis of the insitu joints between segments was undertaken, using headed bars to provide the required anchorages. The pier head was designed using finite element models to confirm the strut and tie behaviour and a prestress layout that minimised external pockets. |
