The confining stress
WebMay 26, 2024 · Under constant stress confining condition, the specimen failed in the ductile mode while the specimen exhibited a sudden and brittle failure behavior under constant stiffness confining condition. The evolution trend of the elastic strain energy was greatly affected by the magnitude of confining stiffness. When the confining stiffness was small ... WebCastro plotted the relationship (see figure below) between effective confining pressure and void ratio at large strains for these undrained, stress-controlled tests. Castro referred to the curved produced by this plot, which is similar to the CVR line for the drained strain controlled tests performed by Casagrande, as the Steady State Line (SSL).

With each certain confining pressure, the different k values have no significant influence on the difference between major principal stress and minor principal stress. However, when the confining pressure is low, high k value shows a low difference …

WebBased on the theoretical and experimental results of this paper, a confining stress path-based compressive strength model will be developed for FRP-confined concrete. The developed model yielded more accurate predictions than existing models based on the results of this paper and previous tests. WebThe confining stress from the steel tube develops slowly even when the concrete stress reaches 80% of its unconfined compressive strength ( Kinoshita et al., 1994 ). Also, with the increase of axial shortening, the efficiency of confinement degrades after the steel tube enters into the inelastic outward buckling.
