Flexural fatigue behaviour of concrete under uniaxial and biaxial stress

摘要: The main objective of this investigation was to study the effect stress states on flexural fatigue behaviour concrete. behaviours obtained from different test methods were compared, including recently developed biaxial flexure test, ASTM C 1550 and four-point bending test. Fourteen specimens cast tested for each method, under both monotonic repeated loadings. strength compared with those recommended by existing design codes. Test results showed that there no significant differences in (i.e. uniaxial biaxial). These suggest tensile concrete may be adopted components subjected loading.
