Overview

In this project influences of the combined impact of time and temperature on the behaviour of FRP materials used to strengthen concrete structures will be studied. The long and short term behaviour of basalt, glass and carbon FRP reinforcement will be investigated.

If the FRP reinforcement is pre-stressed (in tension) before application, the stress state of the composite varies significantly with time.

It is planned:

  1. To study time dependence of the mechanical behaviour of concrete columns strengthened by FRP (basalt, carbon, glass etc threads in epoxy or other matrix)
  2. To study temperature dependence of the mechanical behaviour of concrete columns strengthened by FRP (basalt, carbon, glass etc threads in epoxy or other matrix)
  3. To define the relation between the tensile pre-stress of the FRP reinforcement and composite structure deformations

To study the joint effects of high-temperatures, FRP tensile pre-stressing and long-term loading on the behaviour of FRP reinforced concrete.
