Why Dlubal Software?
The wind, which blows parallel to the surfaces of a structure, can generate friction forces on these surfaces. This effect is mainly important for very large structures.
DIN EN 1998-1 with the National Annex DIN EN 1998-1/NA specifies how to determine seismic loads. The standard applies to structural engineering in seismic areas.
In Germany, DIN EN 1991-1-4 with the National Annex DIN EN 1991-1-4/NA regulates the wind loads. The standard applies to civil engineering works up to an altitude of 300 m.
When it comes to wind loads on building type structures per the ASCE 7, numerous resources can be found to supplement design standards and aid engineers with this lateral load application. However, engineers may find it more difficult to find similar resources for wind loading on non-building type structures. This article will examine the steps to calculate and apply wind loads per the ASCE 7-16 on a circular reinforced concrete tank with a dome roof.
The story drift of a building provides valuable information about its structural behavior under seismic loads.
In Germany, DIN EN 1991-1-3 with the National Annex DIN EN 1991-1-3/NA regulates the snow loads. The standard applies to civil engineering works at an altitude of up to 1,500 m above sea level.

Wind is the only climatic load acting on every single type of structure in the entire world, different from other loads like snow, for example. The wind size depends on the geographical location of the structure. That is one of the main reasons why today’s standards have regional division (wind zones) and consideration of altitude, as well as variation of dynamic pressure depending on the height above ground for a ‘normal’ site, without masking effect.
