: Tendons are tensioned before the concrete is poured. This is standard for factory-precast elements like hollow-core slabs.
Leonhardt encouraged engineers to use partial prestressing rather than full prestressing, allowing for limited, controlled cracking under design loads, which improves structural behavior under ultimate conditions. 2.2. Bonded Tendons
While modern engineers now work with higher-strength materials and advanced software, Leonhardt’s book is still cited for its authoritative treatment of: : Tendons are tensioned before the concrete is poured
The book details several systems and methods Leonhardt pioneered:
Fritz Leonhardt (1909–1999) was a legendary German structural engineer whose career spanned nearly 90 years. He wasn't just a theorist; he was a prolific builder. His portfolio includes: The Stuttgart Television Tower: The world's first concrete television tower. Cable-Stayed Bridges: His portfolio includes: The Stuttgart Television Tower: The
In 1954, Leonhardt formed the consulting firm Leonhardt und Andrä in Stuttgart, which later became Leonhardt, Andrä und Partner. From 1958 to 1974, he served as professor of solid construction at Stuttgart University, teaching reinforced and prestressed concrete design, and was president of the university from 1967 to 1969.

Prestressing is a method of load balancing, not just stress reduction.
