Corrosion of Reinforcing Bars in Concrete
The causes and mechanisms of corrosion of reinforcing bars in concrete are described in terms of the practical issues as well as the electrochemistry. The parameters affecting corrosion are (i) the ingress of aggressive species, such as chlorides, which break down the protective film on the reinforcing bar and (ii) the amount of those species necessary to do so. The former is largely controlled...
متن کاملComputational Homogenization of Fresh Concrete Flow Around Reinforcing Bars
Motivated by casting of fresh concrete in reinforced concrete structures, we introduce a numerical model of a steady-state non-Newtonian fluid flow through a porous domain. Our approach combines homogenization techniques to represent the reinforced domain by the Darcy law with an interfacial coupling of the Stokes and Darcy flows through the Beavers-Joseph-Saffman conditions. The ensuing two-sc...
متن کاملImproving the Development Characteristics of Steel Reinforcing Bars
The bond characteristics of deformed reinforcing bars are investigated ctnd design equations for development and splice lengths are obtained with the goal of improving the bond strength of steel reinforcing bars to concrete. The research includes both experimental and analytical studies. The experimental studies involved evaluating the performance of deformed steel reinforcing bars with differe...
متن کاملBond Strength of Composite CFRP Reinforcing Bars in Timber
The use of near-surface mounted (NSM) fibre-reinforced polymer (FRP) bars is an interesting method for increasing the shear and flexural strength of existing timber members. This article examines the behaviour of carbon FRP (CFRP) bars in timber under direct pull-out conditions. The objective of this experimental program is to investigate the bond strength between composite bars and timber: bar...
متن کاملEvaluation of Properties of Steel Reinforcing Bars for Seismic Design
Capacity design procedure for the earthquake-resistant reinforced concrete (RC) structures is effective when actual member capacities do not greatly exceed the assumed design capacities. Moreover, RC members are expected to undergo large inelastic deformations for adequate seismic energy dissipation. Since flexural capacity and post-yield behavior of an RC member is largely controlled by steel ...
