Prestressed Concrete - Material Properties Excel Sheets Calculators

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 introduces the fundamental material properties that govern the behaviour and performance of prestressed concrete structures. The Excel spreadsheets automate the calculation of concrete and prestressing steel properties, helping users understand how material characteristics influence stresses, strength, serviceability, and long-term structural performance.

Included Excel Examples:

✅ Calculation of concrete compressive and tensile strength properties

✅ Modulus of elasticity of concrete

✅ Stress-strain relationships for concrete

✅ Time-dependent concrete behaviour

✅ Creep coefficient calculations

✅ Shrinkage strain calculations

✅ Prestressing steel stress-strain behaviour

✅ Relaxation characteristics of prestressing tendons

✅ High-strength reinforcing steel properties

✅ Material factors used in design

✅ Evaluation of effective material properties over time

✅ Worked examples following Stephen Foster's design procedures
