API Eurocodes Zoning

Obtain snow, wind and seismic loads from a GPS point with the Eurocodes Zoning API

Determine the climatic (snow and wind) and seismic assumptions of a GPS point to guarantee the safety and durability of your buildings thanks to the Eurocodes Zoning API. Easily integrate complex calculations with our recognised solution.

I am interested View prices

Send your GPS coordinates to the API and receive the snow loads, wind and seismicity zone.

Available countries

A reliable solution designed by our engineering department and used by control offices.

Recognised experience

The Eurocodes Zoning API has been developed in conjunction with our specialist design office, with over 20 years’ experience in structural calculations. Our solution has been tried and tested for more than 5 years, with tens of thousands of queries, and is used by control offices.
Continuous updating

Our API rigorously complies with the latest versions of the Eurocodes and incorporates the national annexes specific to Germany, Belgium, France, Italy and Luxembourg. The reliability and accuracy of our calculations are our major concerns.
Easy to use

You don’t need any technical skills in building or knowledge of Eurocodes standards to integrate the Eurocodes Zoning API into your projects. A simple POST request with your GPS coordinates will give you your first results.
Boost your Excel

The Eurocodes Zoning API lets you integrate our expertise seamlessly into your Excel, Python or other software applications, allowing you to concentrate fully on your core business.

Example of results

Simply enter a GPS point to obtain results, or add land categories and building information to obtain more comprehensive results (orography, Cdir direction coefficient).

Simply specify a GPS point to get current results, or add the land categories and building-specific information to get more comprehensive results, including parameters such as orography c_o,(z) and direction coefficient c_dir.

Snow zone

Obtain the snow zone, the characteristic load of snow on the ground s_k as a function of altitude and return period.
Wind zone

Get the wind zone, the base value of the reference wind speed v_b, the probability coefficient c_prob, the direction coefficient c_dir and a lot of additional information, right down to the peak dynamic pressure q_p.
Seismicity zone

Obtain the seismicity zone and reference ground acceleration a_gR and determine the need for a seismic analysis.
