I am working on silo design to present in a seminar. Normal pressure on the silo wall is to high and need a prestress (post tension). Design is done by using Eurocode. My question is about post tensioning force in combination. According to eurocode-2, prestressed force can be accepted as permanent actions.
Prestressed concrete explained. Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" during its fabrication, in a manner that strengthens it against tensile forces which will exist when in service.
This document, which covers design and construction of concrete silos and stacking tubes for storing granular materi- als, replaced the 1968 ACI Committee 313 Report 65-37 and was adopted as an ACI Standard in March 1977 as ACI 313-77.
CHAPTER 11: PRESTRESSED CONCRETE 11.1 GENERAL (1) This chapter gives general guidelines required for the design of prestressed concrete structures or members with CFRM tendons or CFRM tendons in conjunction with steel tendons. (2) Prestress levels shall be determined to ensure that the structure or member can fulfill its purpose
Concrete is strong and ductile in compression, it is weak and brittle in tension, and hence its response to external loads is improved by pre-compression. Prestressed concrete is a type of Reinforced Concrete in which steel has been tensioned against the concrete. Prestressing Methods. Two different procedures for prestressing concrete were ...
Foreword This Report is intended to serve as a manual of good practice for the design of prestressed concrete flat slabs.. In addition to the recommended procedures, other methods are described for the sake of completeness and to compare different methods of design.
What are the differences between prestressed, pretensioned and post-tensioned concrete? Prestressed concrete is concrete that has had internal stresses introduced to counteract, to the degree desired, the tensile stresses that will be imposed in service. The stress is usually imposed by tendons of indi

Lecture 24 – Prestressed Concrete Prestressed concrete refers to concrete that has applied stresses induced into the member. Typically, wires or “tendons” are stretched and then blocked at the ends creating compressive stresses throughout the member’s entire crosssection. Most Prestressed concrete is precast in a plant.
