That’s very interesting about shielding. ASCE 7 (for the US) explicitly prohibits any reduction in wind loads due to shielding unless a wind tunnel study is performed. Some of the reasonings are that 1) if the adjacent building gets demolished in the future, you wouldn’t be able to count on it anymore, and 2) reports have indicated wind regenerating or picking up speed around the corners of adjacent buildings. Just food for thought. Keep up the great work Brendan!

This covered more exposure classification in the US. For Australia and NZ the reduction from shielding needs multiple building in the wind direction to provide reduction, so the demolition of one building wouldn't affect it. The building surrounding also needs to be taller then your structure to have significant impacts yea Vortexes off building can have detrimental effects on the wind loads. Thanks for the support

Great content Brendan. Living in the Caribbean we have to design for hurricane categories from cat 1 to 5 with wind speeds at 74 to 157+ mph. We recently had a cat 4 passing between barbados and Tobago with effect from the outer bands. Thanks for the video Malik from Barbados.

Topic of the video fits my PhD dissertation thesis: Experimental and numerical analysis of wind pressure coefficient. Cheers!

4:28 - - wind in business districts 4:49 - - as a building gets taller - the wind load goes up vertically 5:10 - - wind must also be calculated for 40x the height + a 500 meter radius around a building.

Awesome content. 🎉 Also can you please do a video about comparison about wind load calculation based on American and European standards. Wind gust speeds, Mean Recurrence Interval etc on different standards confuses the engineers some times. Thanks 😊

I offer a correction: At 2:20 when you are talking about terrain categories, you are referring to the 2011 version of the code. The 2021 version of AS1170.2 reclassified all water surfaces as 1.0 and did away with the 1.5 category. Updated research showed the waves have less effect than previously thought. So the ocean and all bodies of water are now classified as terrain category 1

thanks for the update and correction

Sir do you earn 150k dollars a year in Australia now? Plz reply. Thanks a lot.

Currently, CFD can be utilized to obtain wind load for complex structures.

It can but not often used normally it is done in a wind tunnel
