Figure 8. Tower Structure

3.4 Spatial planning and fit-out

The tower's dual system is designed to withstand substantial wind and seismic loads, while minimizing the quantity of material required and rendering other sustainability methods more accessible. The curved form of the tower is facilitated by the moment frame combined with a ductile reinforced concrete core with composite perimeter columns (See Figure 8). This is tied together by structural steel outriggers and belt trusses at every 30 floors. The load is transferred to the core and perimeter columns by the gravity system of a composite concrete slab on a metal deck supported by structural steel beams (Besjak et al. 2017). The structural system allows efficient integration of architecture and MEP services.

The public realm is accentuated by triple-height arrival spaces. The first 3 floors comprise meeting rooms and lounges overlooking the pedestrian realm along the perimeter. The 7th and 8th floors locate the data centers for the entire campus. 75 department offices are located between the three belt trusses. These intermediate floors are planned to host sky lobbies with wind turbines, refuge terraces, cafeterias, and mechanical services. 05 Executive offices are proposed above the third belt truss. The final 99th floor is divided into 3 spaces – Restaurants, Observation Deck and Wind turbine viewing at the crown [See Figure 9(a) and Figure 10].
