Influence of Steel Rebar Position on Concrete Double-K Fracture Toughness

CODEN: JTEVAB

Abstract

Fracture mechanica is typically used to analyze the crack progration of a concrete material. It can help explore the microscopic crystallographic defects and predict the macroscopic mechanical failure of various solid materials. In this study, rebar positions and notch characteristics effects on the crack progrations were investigated. It was found that the initial fracture toughness values were not related to the rebar positions, but rather the unstable fracture toughness values were slightly associated to the rebar positions. In addition, rebars positions affected the properties of reinforced concrete resistance to the cracking. Moreover, rebars not only improved the ductility of the concrete, but also increased its ultimate bearing capacity.
