Flexural Fatigue Strength of Plain Concrete

open access: yesACI Materials Journal, 1993
This paper presents a new expression to describe the flexural fatigue strength of plain concrete. It incorporates the effects of stress ratio and stress level into the faitgue equation and allows a statistical description of fatigue life in terms of both stress level and stress ratio. A concept of equivalent fatigue life is introduced in the derivation

Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]

open access: yes, 2019
Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.
