This tower’s faceted form and architectural requirements provided unique structural challenges. To accommodate its chiseled shape and open interior atrium, H+P developed the steel structured concept - composed of exterior and interior diagonal columns to resist both gravity and lateral forces. This configuration of vertical supports allows for flexibility in architectural usage. In order to protect the structural system, steel members were designed for fire-proofing materials or to be encased in concrete. Floors are typically composite steel framing, spanning up to 16 m, and constructed with light weight concrete. By reducing this structural weight, the building’s mass is lowered, resulting in both minimized seismic forces and structural costs. The tower’s structural diagonalization provides load paths to four corners of the building’s footprint, allowing for column-free space at ground level.
