Many university libraries offer digitized access or e-book borrowing options through platforms like Delnet or institutional intranets.
For post-tensioned members, the transmission of massive forces from a concentrated anchorage plate into the concrete creates high transverse tensile stresses. The book illustrates the design of bursting and spalling reinforcement using both classical theories (Guyon’s and Magnel’s methods) and standard code recommendations. Target Audience and Educational Value
When the prestress is introduced to the concrete, and only the self-weight of the member acts as a counter-load.
Dr. Rajagopalan has also authored other significant works in civil engineering, including:

Prestressed Concrete by N. Rajagopalan: A Comprehensive Guide to Structural Design
The text details three primary analytical approaches to evaluate a prestressed concrete beam under service loads:
The initial tension put into the steel tendons is not permanent. It reduces over time due to several factors that Rajagopalan explains in detail: Elastic shortening of concrete. Creep and shrinkage of concrete. Relaxation of stress in steel. Friction and anchorage slip (in post-tensioning). Design for Flexure and Shear
Direct concrete stresses ( ) are combined with bending stresses ( ) caused by eccentric prestress and external loads. Many university libraries offer digitized access or e-book

A brief worked intuition (no heavy math) Imagine a simply supported beam carrying a downward load that would normally cause the middle to sag and the bottom fibers to crack in tension. If you introduce an upward (positive) curvature by applying prestress that squeezes the beam into a slight hog (top compressed relative to bottom), the external load must first overcome that compression before any tension appears. If you size the prestress correctly, the bottom never goes into net tension, so cracks don’t form under service loads.
These tendons are stretched using hydraulic jacks.
As noted in university syllabi, this is a frequently referenced textbook in Indian engineering curriculums. Target Audience and Educational Value When the prestress
Official publishers and digital storefronts offer authorized e-book versions that are clean, complete, and fully searchable. 💡 Summary
Prestressed concrete has several advantages over traditional reinforced concrete, including:
Permanent deformation under sustained compressive stress.
