First published in German, the second edition—revised in 1964 and translated into English by C. van Amerongen—is the version that captured the global engineering imagination. It was published by Wilhelm Ernst & Sohn in Berlin and remains a landmark publication for several reasons.

Whether you are a student struggling with tendon profiles or a site engineer investigating an anchorage blowout, finding this PDF is like having Germany’s greatest bridge builder looking over your shoulder. It transforms prestressed concrete from a mathematical exercise into a tangible, buildable art.
Here’s a structured guide for creating or exploring , covering key themes, content formats, audience considerations, and practical tips.
However, the theory was young and often poorly understood. Early texts were laden with complex, abstract mathematics that were inaccessible to the practical engineer. Leonhardt, who had already made a name for himself with the Cologne-Deutz and Manderscheid bridges, recognized that prestressed concrete was not just a calculation method but a distinct structural behavior. His book was born out of a necessity to demystify the technology, presenting it not as a "black box" of elasticity theory, but as an intuitive and manageable engineering tool.

: The text emphasizes understanding short- and long-term deformations, avoiding tensile stresses under dead loads, and the critical importance of fabrication knowledge for designers. Digital Access and PDF Resources
Ultimate Limit State (ULS) and Serviceability Limit State (SLS)
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: : Analysis of high-tensile steel
: He pioneered the system where a bridge is fabricated at an abutment and "pushed" by hydraulic jacks across a valley, which was particularly useful in harsh European climates.
: Analysis of high-tensile steel, concrete strength, and time-dependent properties like creep and shrinkage.
He believed that the designer must intimately understand the construction methods (e.g., precasting, post-tensioning) to optimize the structural design. 2. Key Concepts in Leonhardt’s Design Approach
Each new segment is cast directly against the previous one and post-tensioned together.
: Engineers must account for both short-term and long-term deformations caused by prestressing.
