2.1. Wind Actions

Try these first

1. 1.

   What is the windward side of a structure?

   Hint

   Think about where the wind hits the building.

2. 2.

   What is uplift?

   Hint

   Consider the effect of wind trying to lift the roof.

3. 3.

   What type of pressure does a sloping roof face on the windward side?

   • Negative Pressure
   • Positive Pressure
   • Equal Pressure

   Hint

   Remember which way the wind is blowing.

4. 4.

   True or False: High permeability in a roof can increase net uplift forces.

   • True
   • False

   Hint

   Think about the effect of open gaps.

5. 5.

   Analyze a building with a sloped roof design facing a wind speed of 50 m/s. How should structural engineers adjust their approach to ensure safety from wind loads?

   Hint

   Consider both the angle of wind impact and the material strength needed.

6. 6.

   A vertical cladding panel experiences varying wind forces due to local terrain changes. Explain how these variations influence cladding design and maintenance strategies.

   Hint

   Think about how topography might impact wind flow patterns.
