Title:
Abstract:	Wandelbare Leichtbaukonstruktionen mit Membranen erfreuen sich immer größerer Beliebtheit. Durch eine adaptive Gebäudehülle steigt die Funktionalität des Gebäudes und innerhalb von Minuten kann z. B. ein Sportstadion in eine Mehrzweckarena umgewandelt werden. Im Mai 2019 wurde das Al-Janoub-Stadion in Katar eröffnet. Mit seinem 10 800 m2 großen wandelbaren Membrandach ist es ein Meilenstein in der modernen Stadionarchitektur. Dabei wurde das innovative Konzept des wandelbaren Innendachs optimal in das Erscheinungsbild der Gesamtarchitektur integriert. Innerhalb von 30 Minuten ist das wandelbare Membrandach verfahrbar, sodass der gesamte Stadioninnenraum verschattet ist. Die Möglichkeit der Verschattung ist in einem Gebiet mit starker Sonneneinstrahlung essenziell. Ein wandelbares Membrandach hilft dabei, selbst unter extremen Bedingungen die Temperaturen zu reduzieren und den Nutzerkomfort zu gewährleisten. Games in shade - the retractable roof for the Al Janoub Stadium in Qatar Retractable lightweight structures using textile membranes are used more and more often. The functionality of a building is significantly increased by the implementation of an adaptive building envelope. A stadium for example can be transformed into a multifunctional arena within minutes. The Al Janoub Stadium in Qatar has been inaugurated in May 2019. With its 10 800 m2 large retractable membrane roof it forms a milestone of modern stadium architecture. The innovative concept of the retractable roof has been developed to perfectly fit to the overall architectural appearance. Within 30 min the retractable roof can be closed to provide full shade for the playing field and the stands. The possibility of providing shade is essential in areas with strong solar radiation to reduce the temperature and to provide a certain user comfort.
