Snow and wind experimental analysis in the design of long-span sub-horizontal structures

Abstract

Inadequate analysis of loading conditions and/or structural behaviour is considered to be a prime cause of failure in structural reliability assessment. In order to increase the reliability level of the design process of long-span lightweight structural systems, theoretical analysis must be frequently integrated by in scale experimental investigations combined with monitoring control of the subsequent performance of the structural behaviour. The uncertainties related to the random distribution of live loads on long-span sub-horizontal structures imply very careful experimental loading analysis to calibrate mathematical modelling and evaluate long-term sufficiency of the design.
