Industrial Warehouse Structural Design.

Rigid Frame & Roof Truss Alternative – AS 4100 / AS 1170
Project Overview
Designed and analysed alternative structural systems for a large industrial warehouse located in South-West Sydney. The project involved evaluating a rigid portal frame and a roof truss alternative, including load assessment, preliminary sizing, and stability verification in accordance with Australian Standards.
Engineering Scope
Figure 1. Wind load distribution along portal frame elevation showing varying pressure intensities and tributary spans for lateral analysis.

Figure 2. Critical flange identification under sagging and hogging moments, highlighting compression zones and lateral restraint requirements.
