lumenkuorma

Lumenkuorma is a Finnish term that translates to "snow load" in English. It refers to the weight exerted by accumulated snow on a structure, such as a roof, balcony, or bridge. Understanding and calculating lumenkuorma is crucial in regions with significant snowfall to ensure structural integrity and prevent collapses.

The calculation of lumenkuorma typically involves several factors. These include the geographical location, which determines the likelihood and intensity of snowfall; the roof's geometry, as its slope affects snow accumulation; and the type of snow, as wet, heavy snow is significantly denser than dry, powdery snow. Building codes in snowy regions often specify design snow loads that must be considered during the design phase of new construction and for the assessment of existing structures.

Factors that can influence the actual snow load on a structure beyond the basic calculation include drifting snow, which can create uneven and concentrated loads, and ice formation, which adds substantial weight. Snow guards or fences are sometimes installed on roofs to prevent large snow masses from sliding off suddenly, which can be a safety hazard. Regular maintenance and snow removal, especially for older structures or during periods of exceptionally heavy snowfall, are important practices to mitigate the risks associated with lumenkuorma.
