Original Abstract

The presented paper copes with an experimental validation of a model based on modified Weibull size effect theory. Classical statistical Weibull theory was modified by introducing a new parameter (correlation length l_rho) representing the spatial autocorrelation of a random mechanical properties of material. This modification is here compared with experimental data obtained for two different materials used in civil engineering: unreinforced (plain) concrete and multifilament yarns made of alkali-resistant (AR) glass which are used for textile-reinforced concrete. The behavior under flexural and tensile loading is investigated by laboratory experiments. A high number of specimens of different sizes was tested to obtain statistically significant data which were subsequently corrected and statistically processed. Results of the experiments showed a decreasing average strength with an increasing sample length. Size effect curves were obtained and the correlation length was fitted according to measured data. Results do not disclaim the existence of the proposed new parameter l_rho.

Keywords

Statistical size effect, concrete, multi-filaments yarns, experiment, autocorrelation length.
