Load Generator

Working with the Load Generator

With the load generator you generate the snow and wind loads including all the load combinations in no time. Especially the wind loads according to the Eurocode are extensive and therefore laborious. The load generator will take this work out of your hands. The output specifically shows how the wind loads on the beams are determined and calculated.

Note! Before you can work with the load generator, you need to select the right beam type (load) per beam. You have the option between: floor, left vertical wall, right vertical wall, roof, overhang, wall/parapet. Based on this, the snow and wind loads are calculated. See Beams.

General

The dimensions of the building and the place of the central truss in the building.

Design Working Life The design working life of the building in years.

Height of the Building The height of the building in meters. This value is generated. The height and the depth of the building are the deciding factor for the wind pressure coefficients.

Depth of the Building The total depth of the building (measured perpendicular to the truss plane) in meters. The height and the depth of the building are the deciding factor for the wind pressure coefficients.

Width of the Building The total width of the building (measured in the truss plane) in meters. This value is generated. The height and the width of the building are the deciding factor for the wind thrust.

B - Load Width Truss The width (measured perpendicular to the truss plane) in meters that the truss needs to bear.

A - Distance End Wall to Center Truss The distance end wall - center truss (measured perpendicular to the truss plane) in meters. This distance is important for determining the wind pressure coefficients. An interpolation is executed between the wind pressure coefficients in different zones of the roof.

Snow Loads

Snow loads according to EN-1991-1-3 Select whether the snow load needs to be generated or not.

Wind Loads

Wind loads according to EN-1991-1-4

Wind Zone Dependent on the location of the structure, the wind zone is chosen. This value differs per country.

Terrain Category Based on local circumstances the terrain category is chosen.

Height Above Terrain The height of the building above terrain in meters.

Velocity Pressure Calculated velocity pressure.

Structural Factor Structural factor according to 6.3.

Correlation Setting if wind pressures on facades must be reduced by 0.85. E.g. according to Dutch NAD art. 7.2.2(3).

Wind from Left Select whether the wind has to be generated from left to right.

Wind from Right Select whether the wind has to be generated from right to left.

Wind Perpendicular Select whether the wind should be generated perpendicular (perpendicular to the truss plane).

The internal under- and over pressure is dependent on the size of the holes in the facades.

Generate Loads All the load cases and load combinations for snow and wind are created automatically. You can also change and extend these loads.
