Pre-tensioning systems
In the previous unit we have seen different steps in a pretensioning operation. Tendon wires or strands (formed as a rope type arrangement made of several tendon wires) are stretched and concrete is cast in the moulds, as shown in Figure. When sufficient strength is gained by concrete due to hardening, tendon wires may be cut from outside and jacks may be removed.
Determine the types of losses of prestress A loss of prestress will affect the stress distribution on a section of the member. It is therefore necessary to estimate the probabl
