Hi everyone,
I have a question in regards to 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...

Hi everyone,
I have some questions in regards to the rules stated in the AS/NZS 1170.2 under Section 5 on the Action Combination Factors (Kc). The standard states that when the building has
2 effective surfaces: Kc = 0.9
3 or more effective surfaces: Kc = 0.8
However, I am a little bit...
Hi everyone,
I am an architectural student that has just started learning about wind engineering. I have a bit of a problem trying to understand how the wind pressure works in a building. In what situation will the roof pressure act alone on a building?
Hi everyone,
I just wanted to ask. To get the external pressure coefficient of roofs, for the intermediate values of the ratios and angles, the standard stated that they could be linear interpolated. However, interpolation should only be carried out on values of the same sign. So, does that...
Hi all,
I have a question regarding the determination of the Local Pressure Factor in Section 5 of the AS/NZS 1170.2. I have read a few books regarding this topic but I am still not able to understand the standard. The standard states that the Building Aspect Ratio is calculated as average...
Hi everyone,
I am a bit confused in trying to determine the Kc of a structure using the AS/NZS 1170.2. It states in Section 5 of the standards that internal surfaces with |Cpi| < 0.2 is determined as an ineffective surface. However, in the table for the design cases, it asked how many surfaces...
I have a bit of confusion regarding the rules stated in the AS/NZS 1170 Section 5 on determining the internal pressure coefficient. I am wondering, is the Cpi determined from the table 5.1(A) or 5.1(B) for the whole building? Or is it only used as the Cpi on one surface?
