Tank Wind Buckling AS 2304 Calculation
Engineering Spreadsheet — Instant Download
What This Spreadsheet Does
Checks above-ground water storage tank shells against wind buckling per AS 2304 — the Australian Standard for water storage tanks for fire and other services. The empty tank condition is the critical wind buckling case, and this sheet verifies the shell is adequate or specifies stiffener requirements.
What’s Inside the Excel File
- Inputs — tank diameter, height, shell thicknesses per course, design wind speed, terrain category, material grade, stiffener configuration if any
- Wind pressure per AS 1170.2 reference
- Critical buckling stress per shell course
- Required vs available capacity with utilization
- Intermediate stiffener sizing if shell is inadequate
- Top stiffener / wind girder design
Who This Is For
- Tank design engineers on Australian projects
- Water utility design teams in Australia
- Fire-water tank designers
- EPC teams delivering to Australian, New Zealand markets
Codes & Standards Referenced

Frequently Asked Questions
Fire water only?
AS 2304 is specifically fire-water tanks. Methodology transfers to other above-ground water tanks but specific service standards may differ.
API 650 wind girder vs AS 2304?
Both standards address wind buckling. API 650 is the US/international approach. Use the standard required by your project specification.
