Shenzhen International Airport is located in the south east of China. The terminal has a length of 1.6km and added 78 gates to the existing airport. The building has a 300.000m2 double-layered facade and roof construction with spans up to 80m. Due to the free form design and varying dimensions of the façade panels a parametric development of the geometry was necessary. To manage 60.000 panels attached to a free form and based of different window sizes Knippers Helbig developed a parametric design tool and details that fit every geometric condition.
The structural concept for the concrete substructure was developed in close cooperation with local engineers in order to define a system that fits the architectural image and considers local fabrication standards. Core issues included: the definition of the building grid, beam spans, and the connection of the steel structure to the concrete foundation considering earthquake loads.
The steel structure consists of 450.000 members and allows for high earthquake loads. So called twin bracings are spanning in cross direction for higher stiffness, all other members are following the diagrid in order to achieve a maximum transparency of the facade.
