Prestressed Concrete Structures: During-Tensioning Method

This monograph presents a method for prestressing reinforced concrete structures by applying stress to a freshly laid concrete mix. The technological processes required for implementing this method are examined in detail.

The book outlines a methodology for calculating the strength of compressed concrete with a matrix-frame structure. It provides equations that describe the stress state of reinforcement steel as continuous mathematical functions across its entire load-bearing range. Additionally, it offers an analytical derivation of stress-strain state equations for normal sections of reinforced concrete structures with solid circular and annular cross-sections, based on accepted assumptions.

A practical example of producing prestressed reinforced concrete structures using this during-tensioning method is discussed, along with quality control considerations.

This book is intended for professionals in the construction industry and may also be useful for postgraduate and university students specializing in construction.
