Abstract text:
The combination of Ultra-High Performance Concrete (UHPC) and conventional construction methods (the use of Normal Concrete – NC) results in columns with a high load capacity. Compared with columns made only of UHPC or High Performance Concrete (HPC), they provide a better ductility and superior fire resistance because the external layer of NC reduces the penetration of heat in the core made of UHPC. From the total of 16 columns which were tested in the experimental program, 12 columns had a compound and 4 columns had a simple cross section. An analogy is made between the results of the experimental test and the results achieved with the Finite Element Analysis (FEA) software TNO “Diana”.
Key Words:
Ultra-High Performance Concrete (UHPC); Ultra-High Performance Fibre Reinforced Concrete (UHPFRC); Finite Element Analysis (FEA), Finite Element Model (FEM), concrete columns.
