Abstract

Long span structures 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, whose combination deals with lightweight structural systems. In order to Increase the reliability assessment of long span lightweight structural sys- tem, a knowledge based on a synthetically conceptual design approach Is recommended. The uncertainties related to the large dimension and the eventual movable and/or retractable functions must be considered with special attention during design process. 1 Introduction Long span structures, fixe
