Climatic actions on a canopy roof and a protruding roof corner

摘要

The standard NF EN 1991-1-4[1] and its National Annex[2] define the bases for calculating the wind action on structures. The case of a gable roof is covered in §7.2.5 of the standard[1] and the case of a protruding roof corner in §7.2.1 of the standard[1].The canopy roof is covered in the CNC2M[5] recommendations. The standard NF EN 1991 -1 -3[3] and its National Annex[4] define the bases for calculating snow loads on structures.The case of a gabled roof is covered in §5.3.3.3 of standard[3]. The objective of this article is to present a simple example of how to calculate the action of wind and snow on a canopy roof as well as on a building with a protruding roof corner to describe the methods to be used.
