Prestressed Concrete - Flexural behaviour of uncracked members

Independent engineering spreadsheet developed by East Coast Structural Engineering Consultant Pty. Ltd. The methodology is informed by established prestressed concrete material principles and applicable Australian Standards. Technical reference materials consulted during development include Prestressed Concrete by Robert Warner, Stephen Foster, Andrew Kilpatrick and Rebecca Gravina. This spreadsheet is independently developed and is not affiliated with, endorsed by or published by the textbook authors or publisher.

This excels sheets focuses on the flexural response of prestressed concrete members that remain uncracked under service loading. The Excel spreadsheets automate the calculation of stresses, section properties, and bending behaviour, enabling users to understand how prestressing influences structural performance before cracking occurs.

Included Excel Examples:

✅ Stress distribution due to prestressing force and eccentricity

✅ Combined effects of prestress and external loads

✅ Calculation of section properties and kern distances

✅ Extreme fibre stresses at transfer and service stages

✅ Determination of cracking moments

✅ Load-balancing concept and equivalent prestressing loads

✅ Serviceability stress verification

✅ Assessment of tension-free sections

✅ Worked examples based on textbook design procedures
