Abstract:
The 58-story IB Tower in Kuala Lumpur, Malaysia, posed a number of challenges for DAEWOO Engineering and Construction Co. Ltd, but none more so than the structural concrete elements that will produce the distinctive look of the completed tower. In addition to the central elevator and stair core, the building design includes six mega columns connected by sloping post-tensioned columns in a zigzag pattern. The specification for the finish of the sloping columns required that they be formed without ties. EFCO Formwork design engineers conceived a solution to construct the sloping columns without the need for form ties or substantial amounts of shoring and reshoring.
