In Austria, the characteristic snow load is calculated according to ÖNORM B 1991-1-3 from the snow load zone and the altitude of the site. Due to the Alpine topography, values range from below 1 kN/m² in the east to several kN/m² at high altitudes.
LoCaStatik determines zone and altitude from the address and calculates the snow loads for all common roof shapes and special situations.
ÖNORM B 1991-1-3 divides Austria into snow load zones. The ground snow load results from the zone value and the altitude, with the altitude entering quadratically.
Snow loads increase sharply with altitude. The formula of the standard applies up to a specified altitude; above that, site-specific provisions are required.
The snow load zone is determined precisely from the address, as is the altitude. Both values are shown in the location tool and in the report.
For flat, monopitch, duopitch, vaulted and valley roofs, roof level differences, drifting at walls, trough situations and low eaves.
LoCaStatik determines the zone precisely via the address and shows it together with the altitude in the location tool and in the report.
It increases quadratically with altitude. At high altitudes, values of several kN/m² result. The calculation in LoCaStatik follows the formula of ÖNORM B 1991-1-3 within the permitted altitude range.
In addition to the standard roof shapes, also roof level differences, drifting at walls, trough situations, valley roofs and low eaves – each as a separate module with report.
