The 80-story Index Tower in Dubai houses both residential and commercial spaces, housing about 6,000 residents and office workers. WSP USA’s structural engineers explored optimal structures for the mixed program before selecting the clear, architecturally expressed scheme.

A series of major fins carry the weight of the entire tower and resist all wind loads – their tapering form is a direct response to the need for increased area and breadth at the building base. In the upper half of the tower, residential floors economically use conventional concrete flat slabs by introducing intermediate columns between the fins. At the mid-height lobby level, these columns stop and transfer their loads out to the fins, leaving the office floors below to span an incredible 85 feet column free between the fins.
