Numerical and experimental investigation of structural members made from RC and SFRC

Popis výsledku v původním jazyce

Utilization of steel fibre reinforced concrete (SFRC) for segmental tunnel lining promises potential advantages in comparison to the traditionally reinforced concrete (RC) structures - faster and easier manufacturing, lower risk of corrosion, less damage during transport and installation, etc. However, the practical experience with the SFRC structural members is rather limited (at least in the Czech Republic). Therefore, an experimental program was carried out in order to investigate performance of the SFRC segments - the research program included laboratory tests of full scale tunnel segments made from RC and SFRC under various loading conditions, and also accompanying material tests on SFRC beams. The testing was supported by an extensive nonlinear numerical study modelling the RC and SFRC segments under various loads. Selected results from the experimental and numerical investigations for both RC and SFRC segments are presented and compared. Response of the structural members under service loads and their damage under limit loads are evaluated in order to check and confirm suitability of the SFRC segments for practical utilization.
