Find Your Project's Snow, Wind and Seismic Loads with Google Maps

The Geo-Zone Tool, located on the Snow, Wind and Seismic Zoning Maps webpage, includes zoning maps to quickly determine snow loads, wind speeds and seismic data according to the ASCE 7-16 and other international standards. The search function, based on Google maps, establishes the corresponding location to determine the following:

  • Snow:
    - Ground snow load (pg)
  • Wind:
    - Basic wind speed (V)
  • Seismic:
    - Spectral response acceleration at short periods (Ss)
    - Spectral response acceleration at 1.0-s period (S1)
    - MCEG peak ground acceleration (PGA)
    - Long-period transition period (TL)
    - Risk coefficient at short periods (CRS)
    - Risk coefficient at 1.0-s period (CR1)

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:

Knowledge Base | Load Zones for Snow, Wind and Earthquake

  1. Considering Snow Overhang

    Considering Snow Overhang

    The “Generate Snow Loads” function provides the option to consider snow overhang. Thus, the load of the snow overhang is applied automatically to the eaves using distributed load or several nodal loads.

  2. Figure 01 - Flowchart for Determining cpi

    Determination of Internal Pressure Coefficient cpi for One-Storey Buildings According to EN 1991-1-4

    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.

  3. Figure 01 - Graded Wind Load Over Different Building Heights

    Wind Depending on the Structure Height for Vertical Walls

    The wind loads are regulated according to Eurocode 1 - Actions on structures - part 1-4: General actions - Wind loads. The nationally determined parameters of a respective country can be found in the National Annexes.

  4. Not Treating Snow and Wind Together as Collateral Actions

    Not Treating Snow and Wind Together as Collateral Actions

    According to DIN EN 1990/NA:2010‑12 - NDP to A.1.2.1(1) Comment 2, it is necessary to only apply one of the two climatic actions in the combination expressions for actions according to 6.4.3 and 6.5.3 in the case of places located up to +1,000 m above mean sea level if snow and wind are available as collateral actions in addition to non‑climatic leading action.
