A prestressed concrete structure can be defined as a concrete structure where external compressive forces are applied to overcome tensile stresses caused by unavoidable loads due to gravity, wind, etc. In other words, it is pre-compressed concrete meaning that compressive stresses are introduced into areas where tensile stresses might develop under working load and this pre-compression is introduced even before the structure begins its working life.
A fundamental aim of prestressed concrete is to limit tensile stresses, and hence flexural cracking, in the concrete under working conditions. Design is therefore based initially on the requirements of the serviceability limit state. Subsequently considered are the ultimate limit state criteria for bending and shear. The analysis and design of prestressed concrete is a specialized field, which cannot possibly be covered comprehensively in this research.
Prestressed Concrete Seminar Report
The first report is a technical seminar report submitted in partial fulfillment of the requirements for the degree of Bachelor of Technology in Civil Engineering. In Chapter 1 Background study about the topic, Chapter 2 Pre-stressing materials, and systems, Chapter 3. Pre-stressing and post stressing system, Chapter 4 final process. This Technical Seminar report on Prestressed Concrete is an excellent opportunity for civil engineering students to get to the knowledge of the particular topic.
The second PDF seminar report covers more topics that will be helpful for better understanding. This report also includes the study of members under axial load gives an insight into the behavior of a prestressed member as compared to an equivalent non-prestressed reinforced concrete member.
