Abstract:
Al Bidda (Platinum) tower is located in Qatar and is one of the world’s few twisted towers. The 45 storey tower structure twists 60o through its height, and also varies in width, resulting in a complicated geometry. The structure consists of a concrete core and frame, with steel bracing to the external “diagrid” that resists the horizontal torsions caused by the loads in the sloping external columns. The structural design required careful consideration of the horizontal torsions, and also the long term creep, shrinkage, thermal and elastic deformation effects. As a result some construction stage restrictions were imposed to ensure that long-term load transfers were kept to acceptable levels.
