Tiivistelmä
The commissioner of this thesis is AFRY Finland Oy. The aim of this thesis was to investigate the effect of the snow load on the purlins of a steel structured PVC hall. The purlins are affected by the normal snow load, and the additional snow load caused by the bagging of the PVC fabric and the accumulated snow on the bags, which is usually not considered when dimensioning the purlins of the steel hall. At the moment there are no guidelines in the Eurocodes on how to design a PVC covered steel hall, which could be used as an aid when investigating or designing a hall.
PVC halls have collapsed under excessive snow load in Finland. Usually, they are caused by poorly designed steel structures and underestimated snow loads on them. If designed correctly, PVC halls are cost effective and durable options for different kind of use.
The goal was to find a method that can be used when evaluating the effect of the snow load on the purlins when designing and inspecting PVC halls. As steel structures come in different forms and PVC material has different mechanical properties, the method used here is simplified, but it can give valuable information when inspecting existing halls or designing a new hall.
