Opis

This introduces core concepts and steps for software-based structural design and construction of post-tensioned buildings, illustrated with example designs to Eurocode and American codes, including a column-supported floor system, a beam frame for a parking structure, bonded and unbonded post-tensioning systems, and crack mitigation.

Worldwide growth and application of post-tensioning in recent years is one of the major developments in building construction. The growth is propelled by a burgeoning demand for construction of serviceable and safe buildings. Unlike traditional construction, post-tensioning is based on new design methodology often not covered in traditional engineering courses.

With more than 40 years of experience of study, teaching and work on post-tensioning applications around the world, the author has written this book for students as well as practicing engineers, contractors and academics.

While the book covers the basics and concepts of post-tensioning in simple and clear language, it also focuses on the application and detailed design through real world examples.

Topics of the book include the European and the American building Codes for post-tensioning design. The codes are detailed in the book’s examples such as column-supported floors and beam frames. The book explains and highlights the importance of shortening specific to post-tensioned members and construction detailing for serviceable and safe performance.
