This project included the design of seating on the balcony and a retractable seating system which consists of 18 platforms with 617 seats. The structure has a total width of 25 m and height of 6 m. Depending on the show, the system can be used in various configurations: opened, partially opened and closed. SCIA Engineer was used to analyze the metal structure of the retractable seating. The excellent interaction between the ‘table input’ and Excel enabled us to build a parametric model in Excel to export different models to SCIA Engineer. In general, moveable platforms create a huge challenge for the structural design of the stand: the movability restricts the structural design freedom and the structure needs to be stable with limited deflection in the different structural configurations. With SCIA Engineer a non-linear second order analysis could be carried out of both the opened and closed configurations to ensure a correct functioning of the retractable seating.
