Lightweight structures are widely applied for sport buildings, social buildings, industrial facilities, ecological applications and others. The experience collected during the last decades identified structural typologies such as space structures, cable structures, and membrane structures, as well as new materials being efficient under tension. This contribution 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 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. Some special remarks concerning the influence of detail design on the reliability level are given at the end of the paper. It has been noted that there is a great influence of knowledge base on conceptual design in removing gross human intervention errors from initial design statements. Computer assisted methods of design and analysis allow to generate an interactive design cycle which optimizes the user's synthetical capacities and the analytical computer elaboration power. Sensibility analysis is an extremely powerful tool to determine the influence of parametric design uncertainties for unusual long span structural systems.
