Abstract :
[en] The concept of static wind load is widely used in practice for structural wind design. In this
context, this paper assesses the envelope reconstruction problem stated as follows: find the best set
of static loadings that is optimum to reproduce by static analyses, the envelope values of structural
responses resulting from a formal buffeting dynamic analysis. A solution was recently derived
by means of Principal Static Wind Loads which are well-suited for this problem. The concept is
illustrated with a large stadium roof and the accuracy of the envelope reconstruction is analysed.
