Wind Assessment Standards for Australian Residential Projects (Pt. 2)

Learn how to design wind bracing system to Australian Standards - AS 4055 Wind Loads for Housing and AS 1684.2 Residential Timber Frame Construction

Using the correct wind classification is critical in ensuring a building is designed to comply with the applicable local building standards. In Australia, the two standards that apply are the AS 4055: 2021: Residential Wind Actions and the AS/NZS 1170.2:2021: Structural design actions, Part 2: Wind actions.

However, calculating wind loads for a residential building can be difficult and time-consuming. The parameters that go into wind calculations such as topographic parameters, shielding parameters, and terrain categories are often obtained based on guesstimates and may result in potentially unsafe or costly outcomes during or after the build.

Join Qiming Liu, ClearCalcs' Structural Engineer, in this 2-webinar series on Wind Assessments Standards for residential buildings in Australia.

In the second part of the series, Qiming will give an overview of the wind bracing design workflow to the AS 4055: 2021 and AS 1684.2 requirements. We will discuss the different site characteristics involved in the analysis, the affected building and what to do when your design fall outside the design limitations such as geometric limits, wind loads, torsional irregularities, large openings, etc.

In this webinar, we will cover:
An overview of the workflow for designing a bracing system
-- Determining the "wind class" of your structure (AS 4055)
-- Determining total bracing requirements (AS 4055 / 1684.2 - overlaps them both)
-- Deciding upon the specific bracing type and how to lay it out (AS 1684.2)
Site-specific characteristics for wind assessment
Limitations to the wind bracing system design (geometric limits, wind loads, torsional irregularities, large openings, etc.)
