Abstract (english)
The paper carries out an experimental and numerical analysis of hook-end steel fiber reinforced concrete. The experimental tests are performed on notched beams loaded in 3-point bending using fiber volume fractions up to 1.5 %. The numerical analysis of fiber reinforced concrete beams is performed at meso scale. The concrete is discretized with 3D solid finite elements and a microplane model is used as a constitutive law. The fibers are modelled by randomly generated 1D truss finite elements and the interface between concrete and fibers is simulated by employing discrete bond-slip relationship. The analysis realistically replicates experimental results. In all investigated cases failure is due to the pull-out of fibers. It is shown that with increase of volume content of fibers the effective bond strength and slip capacity of fibers decreases.
Abstract (croatian)
U radu je prikazana eksperimentalna i numerička analiza betona armiranog čeličnim vlaknima s kukama. Eksperimentalna analiza provedena je savijanjem zarezanih greda u tri točke s različitim volumnim udjelima vlakana do 1,5%. Numerička analiza betona armiranog vlaknima provedena je na mezo nivou. Beton je modeliran s 3D solid konačnim elementima, dok je kao konstitutivni zakon korišten mikroravninski model. Vlakna su modelirana slučajno generiranim 1D štapnim konačnim elementima, a veza između betona i vlakana („interface") modelirana je diskretnim bond elementima. Analiza realno odgovara eksperimentalnim rezultatima. U svim slučajevima, do otkazivanja dolazi zbog čupanja vlakana. Pokazano je da se porastom volumnog udjela vlakana smanjuje čvrstoća bonda i kapacitet prokliznuća vlakana.
