In this course, I will explain the full and detailed process of calculating the wind pressure and base bending moment for a medium height building.

The Assessment of Wind Loads for the Design of Structures is based on Australia/New Zealand standard AS1170.2 however the general concept remains the same for every other code. AS1170 has a very detailed and comprehensive process for calculating wind pressures.

I often see people get confused with so many paraments and regulations of the code and so I have decided to prepare this course to provide a clear roadmap for anyone who wants to learn the process step by step.

My general approach in this course is to explain some basic and general concepts of wind load on structures and then I will explain how to calculate these wind parameters and where in the code I am getting these values from in a real-life example. These parameters include

– regional wind speed for different areas of the country,

-Terrain/height multiplier and explaining the definition of different train categories,

– defining Importance level of the building and return period of the wind considering the occupancy and use of the building

– wind direction multiplier,

– Hill-shape multiplier,

– Shielding multiplier

– Site wind speed

– Design wind speed

– Aerodynamic shape factor for different surfaces or parts of the building.

Calculating aerodynamic shape factor requires calculating the external and internal pressure coefficients, area reduction factor, local pressure factor and reduction factor due to parapet, action combination factor, and dynamic response factor for windward wall, Leeward wall, side walls, roof structure, and cladding surfaces of the walls and roof with respect to the two perpendicular directions of the wind.

– Net wind pressure for the two perpendicular directions of the wind.

– Base moment resulting from the wind pressures for the two perpendicular directions of the wind.

– Net wind pressure on claddings which includes wall and roof elements for the two perpendicular directions of the wind.

By the end of this course, you will learn about the fundamental and detailed process of calculating the wind pressure and base moment for structural members and claddings of a medium height building.

My goal is to add value to my students by conveying my professional/practical experience as well as explaining the theoretical concept behind the design, so please do not hesitate to ask if you ask any questions through the message box here or any other social media links which are provided in our page.
