2. Wind Loads on Sloping Roofs and Vertical Cladding

Try these first

1. 1.

   What primary factors influence wind load calculations?

   Hint

   Think about the factors listed in the wind load discussion.

2. 2.

   Explain what uplift pressure is.

   Hint

   Remember the definition provided when we discussed sloping roofs.

3. 3.

   What does wind load refer to?

   • The force applied by gravity
   • The force exerted by wind on structures
   • The weight of the building materials

   Hint

   Consider what external forces impact structures.

4. 4.

   True or False: Suction pressure on vertical cladding is caused by wind.

   • True
   • False

   Hint

   Reflect on the concepts discussed about wind having different effects.

5. 5.

   Given a structure with a sloped roof angle of 45 degrees and wind speed of 40 m/s, calculate the net uplift pressure on the roof surface using applicable formulas. Show all work.

   Hint

   Ensure to reference the appropriate sections of IS 875 for calculations.

6. 6.

   A high-rise building has large vertical cladding panels exposed to winds at significant speeds. Discuss how this can affect both safety and design, including the considerations for suction forces.

   Hint

   Think through how wind impacts each component and how to design against those impacts effectively.
