Partial Factors for Light-Weight Roofs Exposed to Snow Load
Original language description
Collapses of a number of roofs during the winter period 2005/2006 initiated discussions concerning reliability of the roofs exposed to permanent load and snow. The submitted paper provides a critical analysis of present design procedures accepted in Eurocodes, taking into account available measurements of snow loads in the Czech Republic. In a parametric study the load ratio defined as the characteristic snow load over the total characteristic load is considered. Generic steel structural members are designed using alternative sets of partial factors and reliability of the members is verified by a probabilistic analysis. It appears that design based on partial factors recommended in present codes may not guarantee an adequate reliability level, in particular for lightweight roofs. It is shown that reliability-based design or design using a newly proposed partial factor for snow load dependent on the load ratio provides a well-balanced reliability level.
