Behavior of Concrete Under Nonproportional Biaxial Fatigue Stresses with One Constant

This paper discusses the behavior of concrete subjected to biaxial compression and uniaxial fatigue. Tests are performed on 100 x 100 x 100 mm cube specimens. Within the tests, three lateral stress levels – 0, 0.25, and 0.5 – are performed. The paper also reports on the achievement of experimental stress-strain curves, along with a proposal for using empirical relationships to predict the maximum stress level as a function of lateral stress and fatigue life. Results show that increasing horizontal stress leads to failure mode change and an increase in maximum vertical load-carrying capacity. According to the author, failure modes also indicate that concrete presents similar failure patterns under monotonic and fatigue loadings. From experimental results, the author presents a damage model for predicting the behavior of concrete subjected to biaxial fatigue compression. Good agreement is shown in comparing theoretical stress-strain curves with the experimental data.
