Prestressed Concrete - Flexural behaviour in the post-cracking range

Prestressed Concrete - Flexural behaviour in the post-cracking range

This excels sheets explores the behaviour of prestressed concrete members after cracking has occurred and as loads increase towards ultimate strength. The accompanying Excel spreadsheets automate the analysis of cracked sections, enabling users to evaluate strain distributions, tendon stresses, flexural capacity, and failure mechanisms using practical design procedures from Stephen Foster's Prestressed Concrete textbook.

Included Excel Examples

✅ Cracked section analysis of prestressed concrete members

✅ Effects of prestressing steel ratio on strength

✅ Reinforcement contribution to flexural resistance

✅ Ductility assessment of prestressed members

✅ Comparison of under-reinforced and over-reinforced sections
