The structural analysis software RFEM 6 is the basis of a modular software system. The main program RFEM 6 is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members. The program also allows you to create combined structures as well as to model solid and contact elements.
RSTAB 9 is a powerful analysis and design software for 3D beam, frame, or truss structure calculations, reflecting the current state of the art and helping structural engineers meet requirements in modern civil engineering.
Do you often spend too long calculating cross-sections? Dlubal Software and the RSECTION stand-alone program facilitate your work by determining section properties of various cross-sections and performing a subsequent stress analysis.
Do you always know where the wind is blowing from? From the direction of innovation, of course! With RWIND 2, you have a program at your side that uses a digital wind tunnel for the numerical simulation of wind flows. The program simulates these flows around any building geometry and determines the wind loads on the surfaces.
Are you looking for an overview of snow load zones, wind zones, and seismic zones? Then you are in the right place. Use the Geo-Zone Tool to determine quickly and efficiently snow loads, wind speeds, and seismic data according to ASCE 7‑16 and other international standards.
Would you like to try out the capabilities of the Dlubal Software programs? You have the opportunity to do so! The free 90-day full version allows you to thoroughly test all our programs.

Our best experience has been with Google Chrome. Try it out. After that, the Geo-Zone Tool should work again without any problems.
The raw data comes from DIN EN 1998‑1/NA:2021‑07, including the additional digital content. The GPS coordinates and the response acceleration SaP, R in the plateau area of the response spectrum are available in the form of an Excel table. It shows the GPS coordinates for the latitude and longitude in decimal degrees with an accuracy of 0.1°. The geo-zone tool also works with a grid size of 0.1°×0.1°. The values from the additional digital content are defined as a center of each cell. The result of the search query is then taken from the corresponding cell. Intermediate values are not interpolated nor extrapolated. Therefore, it may happen that the color range does not correspond the result from the cell, because the curves do not follow the grid, but lie on a separate layer. This layer has thus no influence on the results and is only used for a better overview.
Example:City: Ludolf Camphausen Street in Cologne
As you can see in the image, the location in the cell is located at 6.9° east and 50.9° north. Thus, the location you are looking for gets a response acceleration of 1.7144 m/s², as it is not interpolated.
The differences between our snow load map and the HORA web application result from the interval of the data used. Our application strictly refers to the current standard ÖNORM B 1991‑1‑3:2022‑05 with an interval of 0.5 kN/m².
The HORA map, on the other hand, uses an interval of 0.1 kN/m². Thus, the Dlubal Geo-Zone Tool outputs more conservative, strictly standard-compliant values.
The images show the difference for the same coordinates at an example location in Austria. The eHORA map is shown above; our Geo-zone tool is shown below.
If the location is specified by latitude and longitude, use the decimal format in the online service. Entries using "degrees, minutes, and seconds" and "degrees and decimal minutes" are not accepted.
Example:
Latitude: 49.435°Longitude: 12.590°
Notation as decimal degrees:
49.435, 12.590
The basis for calculating a snow load is a snow load zone where the structure is located. The best way to determine the snow load zone as well as the characteristic value of the snow load is to use our online service, Geo-Zone Tool for Load Determination. You can find it on the Dlubal Software website:
Snow Load, Wind Speed, and Seismic Load Maps
In addition to the snow load zone, this tool can determine a wind zone as well as an earthquake zone for any location. In addition to the load maps of Germany, the Dlubal Software web application provides many other countries and standards to select.
