Reinforcement made of glass fibre reinforced plastic – Basics and Application

ABSTRACT: Mechanically high-loaded ceiling and floor constructions made of reinforced concrete are very often subject to special requirements, e.g. with regard to corrosion resistance, resistance against chemical attacks or installation of inductive control systems. In these cases, reinforcing ars made of glass fibre reinforced plastic (GRP) represent an alternative to noncorrosive steel or statically operant fibre reinforcements. After a short introduction to the elemental basics for design of floor constructions fit for traffic and reinforced with GRP-bars, examples of applications carried-out will be presented. In this connection, the issue of the relevant requirements for the construction in each case as well as the difference regarding material properties of the GRP reinforcement compared to conventional construction steel will be addressed in particular
