The fatigue tests of concrete have been conducted with constant confined stress, including compression, tension and alternate tension–compression fatigue loading. Based on the results of experiment, the equations of S–N curves under certain lateral stress were established and fatigue failure criterions for different loading cases were proposed. Thus according to the S–N curves, the fatigue reduction...
To meet the requirement of nonlinear analysis and design for mass concrete structures, the mechanical characteristics of mass concrete specimens 25 × 25 × 40 cm with three-graded aggregate 5–80 mm under biaxial compression-tension and triaxial compression-compression-tension was studied experimentally with the multiaxial concrete apparatus. In comparison with the corresponding wet-screened concrete...
