Profile

Sándor is a Marie Curie Early Stage Researcher at the Budapest University of Technology and Economics, since September 2014. He is a Civil Engineer from the Technical University of Cluj-Napoca and has worked in the design of concrete bridges for highways and railways. He is studying in his research project the bond behaviour of FRP (Fibre Reinforced Polymers) bars in RC (Reinforced Concrete) elements in order to develop improved design model for the bond of FRP internal reinforcement.
 

Recent activities and achievements

Project title: Bond and Anchorage of FRP Bars in RC Elements

Objectives:

  • study the mechanics of bond between FRP rebars and concrete
  • analyse the influence of the most important parameters on the bond performance of FRP rebars
  • develop database collecting available experimental data
  • update experimental database with own results in case of parameters where this is needed (e.g.: bond of FRP rebars in fibre reinforced concrete (FRC), effect of service and elevated temperature on the bond behaviour of FRP rebars)
  • validate existing models
  • develop improved design model

Tasks and methodology: The bond performance of FRP rebars in concrete depends on a number of parameters like: strength and type of concrete, surface configuration of the rebar, type of fibres, loading as well as service temperature and many others. Although several models have been developed to predict bond behaviour, none of them is generally accepted. Extensive further research is still needed. In this work experimental, analytical and numerical studies are performed aiming a better understanding of the effect of different parameters on bond of internal FRP rebars targeting to develop an improved design model.

Expected results: 

  • contribute to the existing experimental database 
  • validate existing models and if necessary to develop improved model

COST Action TU1207

Action TU1207 leverages the already large amount of work carried out on the use of composite reinforcement for structural applications by individual research teams and existing learned groups. Action TU1207 was established in 2013 and operated until 2017. During these four years the Action aimed: to coordinate European research in...
