PE2.1 · Application of established engineering methods
Civil / structuralWeak — demonstrates nothing
The project involved the design of a 12-storey commercial building. The design team used ETABS to model the structure and the design was completed as per Australian standards. My role was to assist the senior engineer with the analysis.
Strong — evidences the element
I developed the ETABS model for the 12-storey moment frame and applied the load combinations from AS/NZS 1170.0. My analysis returned an inter-storey drift of 1/380 under serviceability wind, exceeding the 1/500 limit I had adopted from the client brief. I proposed relocating two columns to shorten the 11.4 m span, hand-checked the revised drift using a portal-frame approximation, and confirmed 1/620 in the updated model. The change was adopted at the design review.
