Prestressed Concrete - Flexural strength analysis

Prestressed Concrete - Flexural strength analysis

This excels sheets examines the behaviour of prestressed concrete members after cracking has occurred and focuses on the structural response as loads approach ultimate capacity. The Excel spreadsheets automate the complex calculations associated with cracked section analysis, allowing users to evaluate strength, ductility, stress development, and failure mechanisms efficiently.

Included Excel Examples:

✅ Cracked section analysis

✅ Determination of neutral axis depth after cracking

✅ Strain compatibility calculations

✅ Stress distribution in concrete and prestressing steel

✅ Evaluation of tendon stress at ultimate load

✅ Ultimate moment capacity calculations

✅ Bonded and unbonded tendon behaviour

✅ Reinforcement contribution to flexural capacity

✅ Load-deflection behaviour after cracking

✅ Ductility assessment of prestressed members

✅ Identification of flexural failure modes

✅ Worked examples based on Stephen Foster's design procedures
