SIZE EFFECT, TOUGHNESS AND FRACTURE ENERGY FOR REINFORCED STEEL FIBER CONCRETE
Abstract :
Double cantilever beams elements are produced from reinforced steel fiber concrete e=c/5 and e=c/10 eccentric compressive loads paralel to cantilever axes in which c is cantilever width is applied. Specimen thickness t is constant and 30 mm. Other sizes are geometrically similar with ratio 1:2:4. In this, size effect is investigated in specimen series. Two horizontal and one vertical displacemens are measured for each specimens. Oppening displacements are found for adding to horizontal displacements for each cantilever ends. Test results are analysed for size effect and paramaters of size effect are found and so bilogarithmic plots of size effect are prepared for each series.
