Title:
Abstract:	Long span roofs are today widely applied for sport, social, industrial, ecological and other activities. The experience collected in last decades identified structural typologies as space structures, cable structures, membrane structures and new - under tension - efficient materials which combination deals with lightweight structural systems, as the state of art on long span structural design. In order to increase the reliability assessment of wide span structural systems a knowledge based synthetic conceptual design approach is recommended. Theoretical and experimental in scale analysis, combined with a monitoring control of the subsequent performance of the structural system, can calibrate mathematical modelling and evaluate long term sufficiency of design. Weitgespannte Dächer werden heute in großem Umfang für sportliche, industrielle, ökologische und andere Aktivitäten verwendet. Aus der Erfahrung der letzten Jahrzehnte sind typische Konstruktionsweisen entstanden wie Raumtragwerke, Seiltragwerke oder Membrantragwerke, die als Stand der Baukunst für den Entwurf weitgespannter Überdachungen gelten. Zur Verbesserung der Zuverlässigkeitsanalyse wird ein wissensbasiertes, synthetisches Entwurfskonzept empfohlen. Die theoretische und experimentelle Analyse des Tragsystems wird kalibriert, indem das Verhalten des ausgeführten Bauwerks mit einem Monitoring-System überwacht wird. Damit gelingt es, zusätzlich die Brauchbarkeit der Entwurfsmethode für die gesamte Lebensdauer des Bauwerks zu bewerten.
