PRESTRESSED CONCRETE STRUCTURES UNIT-1 INTRODUCTION – THEORY AND BEHAVIOUR 1. Define prestressed concrete. 2. What are the advantages of PSC construction 3. Define Pre tensioning and Post tensioning 4. What is the need for the use of
Prestressed concrete structures can be classified in a nuer of ways depending upon the feature of designs and constructions. Pre-tensioning : In which the tendons are tensioned before the concrete is placed, tendons are temporarily anchored and tensioned and the prestress is transferred to the concrete after it is hardened.

2.1 Introduction Prestressed concrete is one of the leading materials in modern construction of the 21st century, yet the concept of prestressing has been employed long before we could figure out a way to apply it to structures. Traditional examples include a
This work presents a proposal of the new numerical three-dimensional (3D) model for describing the nonlinear behaviour of concrete in reinforced and prestressed concrete structures.

The tanks are designed as double skin structures. The external prestressed concrete shell carries all mechanical loadings. The internal skin is made of a double layer laminate, where a monitoring system is able to detect any damage in an internal laminate layer.
A general parabola may be defined as y = ax 2. . . . (1) The approximate constant curvature of this curve may be defined as- K » d 2 y/dx 2 = 2a . . . . (2) In continuous prestressed concrete structures where cable profile changes its curvature several times, each
Terminology and Prestressed Concrete materials The introduction of prestressing in reinforced cement concrete is done by tensioning steel reinforcement IS:1343 deals with prestressed concrete structures.
11/dez/2013 - Prestressed Concrete Slab A hollow core slab, also known as a voided slab or hollow core plank, is a precast slab of Prestressed concrete typically used in the construction of floors in multi-story apartment buildings. A Hollowcore slab offers the ideal structural section by reducing dead weight while providing the maximum structural efficiency within the slab depth.
