Structural principles - Loads

Primary loads

Calculating loads
Windward/Leeward
A diagram shows wind flow affecting a building. The wind flow is from left to right.
The left side of the wall has windward pressure blowing on it. The left side of the roof has windward pressure blowing on it. On the right side of the building, the roof has leeward pressure flowing from the roof. The right wall of the building has leeward pressure flowing from the wall.
Wind load rates
The measurements of the building shown is as follows:
•	height of the building is 6 m
•	length of the building is 9 m
•	width of the roof is 12 m.
The wind load rates which affect the building are as follows:
•	left wall + 1.5 kN/m2
•	left roof + 0.8 kN/m2	
•	right room - 1.5 kN/m2
•	right wall - 0.8 kN/m2.
