Geo-Zone Tool for Load Determination

Why Dlubal Software?
Wind Simulation & Wind Load Generation
It's getting windy here! Send your structures to the digital wind tunnel using the stand-alone program RWIND 2. It simulates wind flows around structures, regardless of whether they are simple or complex.
You can easily import the generated wind loads acting on these objects into RFEM or RSTAB and use them for your further calculations.
You should never neglect the environmental influences. The Geo-Zone Tool, located on the Snow, Wind and Seismic Zone Maps webpage, includes special zoning maps. Use these maps to quickly determine snow loads, wind speeds, and seismic data for many countries according to ASCE 7, NBC, Eurocode, and other international standards. Here you can find everything quickly at a glance.
The search function, based on Google Maps, establishes the corresponding location to determine the following:
- Snow:
- Snow load zone
- Characteristic value of snow load sk - Wind:
- Wind zone
- Fundamental basic wind velocity vb,0
- Basic velocity pressure qb - Seismic Actions:
- Seismic zone
- Reference peak ground acceleration agR
- Subsoil class, and so on - Tornados (USA only):
- Design wind speed V
Use the print function to get an overview of all input values for snow, wind, and seismic actions required for the load calculations.
Although the data can be manually transferred to external programs, an additional web application is available for automated data transfer. Of course, that makes things a lot easier for you.
The Geo-Zone Tool operates with map data and services provided by Google LLC. These Google services are not provided free of charge, which requires you to assume this financial responsibility.
For unrestricted map use, purchase a Geo-Zone Tool package in the Dlubal Webshop:
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.
