🌬️3. Perform a Site-Specific Analysis

Site-specific conditions are a core part of Eurocode-compliant structural analysis. In this step, you’ll learn how to automatically generate wind profiles based on the site's location.

📍 Why It Matters

Eurocode requires that you consider site-specific conditions:

• Terrain category (e.g. open sea, suburban, forest)

• Orography effects (e.g. hills, escarpments)

If you're not accounting for these, you may:

• Be overly conservative, rejecting co-locations that could be accepted

• Or worse, underestimate loads, risking structural non-compliance

🛠️ Step-by-Step Instructions

1. Select the location tab and input the coordinates of your site. Example: 62.45246, 6.38183.

2. Select the correct national annex.

Shapemaker supports a wide range of national annexes and standards and are continuously adding more.

1. After saving, press Automatic wind profile to perform an automatic site specific assement. This includes

• Finding the Fundamental basic wind velocity based on local wind maps

• For each wind direction, finding the Terrain Category

• For each wind direction, calculating the Orography factor

All site-specific values can be overruled by the user by clicking Edit wind profile

If you have precise updated wind data for a site, you can upload and use that data!

✅ You Now Have

• A site-specific wind profile for your structure according to your national annex

• Terrain and orography effects integrated into your analysis
