Fritz Leonhardt was born in Stuttgart, Germany, on July 12, 1909, and died on December 30, 1999. He studied civil engineering at Stuttgart University under renowned professors such as Emil Mörsch and Otto Graf, and later pursued graduate studies at Purdue University in the United States. His career spanned six decades, during which he made major contributions to 20th-century bridge engineering, particularly in the development of cable-stayed bridges.
With 19 robust chapters, the book is structured to guide the reader from fundamental concepts to sophisticated design and construction practices. The table of contents reveals a logical progression:
Leonhardt’s work is grounded in the principle that prestressing is an "active combination"
The 2nd edition (1964) contains approximately 677 pages and was published by W. Ernst. Fritz Leonhardt was born in Stuttgart, Germany, on
A critical contribution of Leonhardt's text is the exhaustive treatment of prestress losses. A tendon never retains its initial jacking force indefinitely. Leonhardt categorized these losses into immediate and time-dependent phenomena:
Concrete is cast with internal ducts. Once the concrete gains sufficient strength, steel tendons are threaded through the ducts, tensioned with hydraulic jacks, and anchored mechanically. Load Balancing and Stress Control

Fritz Leonhardt (1909–1999) was a legendary German structural engineer and one of the foremost pioneers of 20th-century civil engineering. He co-founded the renowned engineering firm Leonhardt, Andrä und Partner (LAP) and served as a professor at the University of Stuttgart. A critical contribution of Leonhardt's text is the
