At 441.8m tall, Kingkey 100 is the 2nd tallest building in Shenzhen, and an iconic landmark addition to Cai Wuwei, Luohu District in Shenzhen.
The tower houses 100-storeys of mixed-use commercial, retail and hotel facilities. One basement retail floor that is connected directly to a metro station, leads to over 70 storeys of grade-A office space, 20 storeys of a luxury six-star hotel, and encased in the crowning sky garden of the top three floors, there will be a variety of fine dining choices with sweeping views of Shenzhen.
Arup led the multi-disciplinary engineering up to the preliminary design stage. Given the slender nature of the building, up to a slenderness ratio of 9.5, our team of structural engineers designed a solution that combines three different kinds of structural systems to ensure lateral stability.

Performance-based wind and fire engineering design
We also led performance-based wind and fire engineering design for the project. During our performance-based wind engineering design, we invited the client to experience and then accept the anticipated peak acceleration of the building using a motion simulator operated by the HKUST, and have a performance-based inter-storey drift of h/450 – codified limit is h/500 – approved by the formal expert panel.
The tailor-made fire engineering design goes above and beyond the existing building codes. Arup’s fire engineers successfully proposed a fire safety strategy that pushed the separation between refuge floors to 19-storeys, four more than the codified requirement of 15-storeys.
