Domes are best killer to wind pressure explained:

Experimental study carried out on the models of low-rise buildings with domical roofs. Wind pressure measurements are made on rigid models by placing them in an open circuit boundary layer wind tunnel as per below figures:








Conclusions:

1. Wind pressure distribution on the surface of a domical roof

is generally suction in nature.


2. Maximum suction occurs near the peak of the dome which

reduces both towards windward side and leeward side.


3. A small strip near the base of single dome on windward

side is subjected to pressure although of small magnitude(yellow highlight).

That why dome shape skylights are the best killer to wind pressure.



Hope this was useful, want to know more information about light weight structures please do not hesitate to contact us.
