Geo-Zone Tool: Snow, Wind, and Seismic Zone Maps
Find Your Project's Snow, Wind and Seismic Loads with Google Maps
Further Information
Why Dlubal Software?
Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
The Geo-Zone Tool, located on the Snow, Wind, and Seismic Zone Maps webpage, includes zoning maps to quickly determine snow loads, wind speeds and seismic data according to Eurocode and other international standards. Seismic Standards
The search function, based on Google maps, establishes the corresponding location to determine the following:
- Snow:
- Snow load zone
- Snow load sk - Wind:
- Wind zone
- Basic wind velocity vb,0
- Basic velocity pressure qb - Seismic:
- Seismic zone
- Peak ground acceleration agR
- Subsoil class, etc.
Although data can be manually transferred to external programs, an additional web application is available for automated data transfer.
The Geo-Zone Tool operates with map data services provided by Google LLC. These Google services are not provided free of charge which requires all users to assume this financial responsibility.
For additional map use, purchase a Geo-Zone Tool package in the Dlubal Webshop:
- Geo-Zone Tool | 500 Requests
- Geo-Zone Tool | 5000 Requests
These packages are not limited to one user but can be used by all employees affiliated with the Dlubal company account.

Nonlinear Material Law for Membranes
In RFEM, there is an option to couple surfaces with the stiffness types "Membrane" and "Membrane Orthotropic" with the material models "Isotropic Nonlinear Elastic 2D/3D" and "Isotropic Plastic 2D/3D" (RF-MAT NL add-on module required).
This functionality enables the simulation of the nonlinear strain behavior of, for example, ETFE foils.
