TLDR
In this paper, the state of stress in the concrete due to bond forces from deformed reinforcing bars is analyzed and a concrete ring model is used for determination of the cracking resistance of the concrete cover.Abstract:
Synopsis The state of stress in the concrete due to bond forces from deformed reinforcing bars is analysed. For determination of the cracking resistance of the concrete cover, a concrete ring model is used. The stresses are calculated for an elastic stage, a plastic stage, and an elastic stage with internal ring cracks. The appearance of the concrete cover cracks along the deformed bars in the bond zones for normal cover thickness can be determined by using the mean of the values obtained for the two last stages. The partly cracked elastic stage gives cracking loads just on the safe side.read more

Continuum damage theory - application to concrete
TL;DR: This paper presents a review of the different models for concrete based on continuum damage theory, formulated at the Laboratoire de Mecanique et Technologie (Cachan, France), and the numerical implementations performed give a good description of the failure process as well as an accurate prediction of the behavior of concrete and reinforced concrete structures.

A model for prediction of time from corrosion initiation to corrosion cracking
Tamer El Maaddawy,Khaled Soudki +1 more
TL;DR: In this article, a mathematical model that predicts the time from corrosion initiation to corrosion cracking is presented, where a relationship between the steel mass loss and the internal radial pressure caused by the expansion of corrosion products is developed.

Influence of Matrix Ductility on Tension-Stiffening Behavior of Steel Reinforced Engineered Cementitious Composites (ECC)
Gregor Fischer,Victor C. Li +1 more
TL;DR: In this paper, the effects of composite ductility on the steel reinforced composite deformation behavior are experimentally studied and contrasted to normal reinforced concrete (RC), where the substitution of brittle concrete with an engineered cementitious composite (ECC), a particular type of HPFRCC with strain hardening and multiple cracking properties, has shown to provide improved load-deformation characteristics in terms of RC tensile strength, deformation mode, and energy absorption.
