    Net Pressure on Buildings

    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...

    Action Combination Factor

    Hi Agent666, I apologize for the late reply and thank you so much for your explanation.

    Action Combination Factor

    Dear Agent666, Thank you for your reply. So, does that mean it the diagram has nothing to do with the location of the openings? For example design case 1 applies if the location of the opening is on the windward and leeward wall?

    Action Combination Factor

    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...

    External Pressure Coefficient (AS/NZS 1170.2)

    Dear hokie66, Thank you very much for the explanation. It's very helpful.

    External Pressure Coefficient (AS/NZS 1170.2)

    Dear hokie66, Does that mean there is no Cpe when the horizontal distance is from 2h to > 3h when h/d is >= 1.0?

    External Pressure Coefficient (AS/NZS 1170.2)

    Dear apsix and hokie66, Thank you very much for the explanation. Just one last question, I was wondering about the linear interpolation for the gable roof when the h/d >= 1. It states in Note 2 that the values in parentheses are for interpolation purposes. Does that mean that for value 2h to...

    AS/NZS 1170.2 : Action Combination Factor (Kc)

    Dear Toby, I apologize for asking you again. I just wanted to know what constitute as surface as effective? For the internal surface I know that it is effective if |Cpi|> 0.2. But what about the other surfaces? Is it based on the situation and how the wind load acts on the building as shown in...

    Wind Pressure on Roof

    Dear hokie66, Thank you for your reply and explanation. I could understand it better now. If that's so, does that mean that if the pressure acts like the image below: There is an opening in both the leeward and windward wall only? And for the image below, there are openings on the windward...

    Wind Pressure on Roof

    Dear JedClampett, Thank you for your explanation. I could kind of understand it now.

    Wind Pressure on Roof

    Dear JedClampett, Thank you for your reply.I was actually wondering about a situation like the image below. I'm not too sure in what condition will cause the pressures to act in such a way.

    Wind Pressure on Roof

    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?

    External Pressure Coefficient (AS/NZS 1170.2)

    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...
