Net Pressure Coefficient

Net Pressure Coefficient

Net Pressure Coefficient

Hi everyone,

I have a question in regards to the calculation estimating the effects of openings on a building to the pressures acting on buildings. To calculate the effects of locating openings on a building do we get a pressure resulting from the net pressure coefficient of the Cpe and the Cpi? To calculate the pressure resulting from the net pressure, do /i just try to get the aerodynamic shape factor using the Cpn? Thank you in advance for your help. I will appreciate it very much.

RE: Net Pressure Coefficient

For an enclosed building with openings it's the sum of Cpe and Cpi on a surface. Depending on the size of the opening relative to any openings on other faces Cpi can be equivalent to Cpe.
