✦ Synopsis

The size effect of concrete strength has been analysed by statistical theories of brittle materials in this paper. On the basis of available theories and experiments, normal distribution was used in preference to any other. The use of Weibull's theory in a non-uniformly tensile stress state has been discussed in this paper, then the authors proposed a new method to count the volume of tensile stress for beams and eccentric loading columns. Finally, we got a good coincidence between the tested and theoretical calculated results for cubic, prismatic compressive specimens, splitting specimens and fracture specimens.
