Estudo numérico e experimental da distribuição das fibras de aço em vigas de UHPFRC

Abstract: O concreto de ultra-alto desempenho (UHPC, sigla em inglês) é um material que apresenta alta resistência à compressão e durabilidade. Quando reforçado com fibras de aço (UHPFRC, sigla em inglês), passa a exibir um comportamento dúctil, alta resistência à tração e à flexão. A distribuição das fibras influencia significativamente o comportamento mecânico e estrutural desse material, sendo fundamental considerá-la nos estudos experimentais e numéricos.Entretanto, experimentalmente, há poucas investigações sobre a… Show more

“…Figure 17 shows a comparative analysis between three mixtures used to determine the compressive strength of UHPC. One of these mixtures represents the theoretical results obtained in this research, while the others correspond to experimental studies carried out by Oliveira [16] and Zhang [34]. UHPC mixtures for compressive strength based on Oliveira [16] and Zhang [34].…”

“…Ultra-high-performance concrete is distinct from conventional concrete due to the inclusion of ultrafine granular components with a maximum diameter of less than 2 mm. These materials include Portland cement, fine sand, silica fume, and quartz powder [7,16]. If the concrete contains granular materials with particles larger than 2 mm, such as coarse aggregate, it can cause heterogeneity.…”
