166 Category 4: Special Projects 4 Canopy - Shenzhen, China SE Contact Katrien Vandermarliere Address TerHulpsesteenweg 181 1170 Brussels, Belgium Website www.ney.be Ney & Partners is a structural engineering consultancy and architectural office. An active vision of civil engineering that integrates different disciplines is what motivates us. The foundation of a successful project is the synthesis of all contextual elements. We do not view the boundary conditions as obstacles but as fuel for our creativity. Our motto is ‘high engineering’ instead of ‘high tech’: effective engineering that adds value by eliminating the non-essential. Owner Gemdale Dabaihui Architect Ney & Partners Engineering Office Ney & Partners Construction Period 01/2016 - 04/2016 The Futian District in downtown Shenzhen, South China, is undergoing a process of complete transformation. In the central plaza, the canopy has to temper the climate during hot summers, be a medium of communication, and become an iconic symbol of the new district. The structure integrates 3 technical chimneys as columns. From their 15 m high top, it develops into a continuous surface of over 1,800 m2. The geometry is induced by a form-finding computation in order to optimize the stress distribution across the steel network. These structural elements are organized into a set of Fermat’s spirals, divided into ladders, to be prefabricated in the workshop and connected on site. 5,000 steel leaves play with the lights. SCIA Engineer has been used to create a 3D analytical model made out of beam elements for the entire canopy. The structure is divided into 3 parts: the columns, the cores and the roof. The geometry has been created through the use of the ‘import dxf/dwg” function. The steel plates of the roof have been optimized using the “Productivity toolbox” to export the results to a custom Excel file and then the “Table input” functionality to update the geometry (cross-sections). Stability and dynamic analyzes have been performed to check the good holding of the structure. The efficiency of the computation process allowed us to compare different geometries and explore different structural solutions to reach an efficient and iconic design. Ney & Partners
