Finite element analysis for the structural behaviour of paving flags made by oc and uhpfrc

Ultra High Performance Fibre Reinforced Concrete (UHFRPC) having over 150 MPa compressive strength and 15-40 MPa flexural strength is considered as the latest generation of concrete technology and highly advanced performance compared with other high strength concretes. UHPFRC is therefore effective in use for the structural components carrying flexural loads such as paving flags. This paper presents the research outcome based on finite element analysis modelling of paving flags made by UHPFRC compared with ordinary concrete (OC). A model was created using finite element analysis (FEA) package, it comprises subbase, sand bedding, paving flag and loading plate. Loads were applied at various values to investigate the structural behaviour of paving flags, sand bedding and subbase layers. The modelling results agreed well with the experimental results.
