Balkar av Hoeghallfast Betong Belastade med Impulslast. Brottmekanisk Provning av RILEM-Balkar (High Strength Concrete Beams Subjected to Impulse Load)
The report presents an experimental investigation of plain concrete beams subjected to static and dynamic loading. Specimens of normal, medium, and high strength concrete were made. The main objective of the investigation was to study the dynamic effect on high strength concrete beams subjected to an impulse load. Another aim was to investigate the strength and the ductility of fiber reinforced high strength concrete beams made with energy modified cement. The results from these tests were compared with the results from tests on corresponding fiber reinforced normal strength concrete made with standard cement. The results show that, for the investigated concrete types, the flexural tensile strength increases while tne fracture energy does not increase with increasing compressive strength. Furthermore, the results indicate that the flexural tensile strength and fracture deformation of plain concrete subjects to dynamic loading does not significantly change in comparison with corresponding loading. However, a major increase of the flexural tensile strength was obseved for both fiber reinforced normal and high strength concrete when subjected to dynamic loading and compared with static tests.
