The results may be of a particular interest to the specialists in the modern design of load bearing glass constructions. The features of the used flexural tests and the statistical analysis of the measured strength data were described. Originality/value: A comprehensive overview of the existing methods for glass strength testing was presented. multilayered glass plates working on bending under static loading). Practical implications: The obtained strength data is needed for designing glass load bearing constructions subjected to actual operating conditions (e.g. For the guaranteed strength of glass used for structural purposes it is necessary to conduct strength tests of the glass from each batch under conditions that closely correspond to actual operating conditions. Research limitations/implications: The maximum flexural strength of glass highly depends on the surface condition, and therefore the strength of the glass of different batches is variable whatever the case may be. The characteristic values of the glass strength, corresponding to the 5% fractile value, in accordance with the test evaluation procedure were 23.71 MPa, 31.98 MPa, 53.43 MPa for the first, the second and the third test series, respectively. The Weibull modulus, which is the measure of flexural strength variation, was between 2.04 and 5.23 at the coefficient of determination R2 greater than 90% for all series. 3PB(V) samples with vertical orientation demonstrated the flexural strength similar to that of 3PB(H) samples with horizontal orientation. Findings: The experiments performed on nominally identical glass specimens revealed a wide range of flexural strength values, from 39.77 MPa to 171.71 MPa at a loading rate of not more than 1.05 MPa/s. A two-parameter Weibull distribution was applied as an appropriate model to describe three strength data sets for glass. Design/methodology/approach: Twelve glass samples of three series were tested by three-point bending with horizontal ‘3PB(H)’ and vertical ‘3PB(V)’ orientation of samples. In addition, step-by-step guidelines for the strength data analysis using a two-parameter Weibull distribution are given. Purpose: The aim of the study is to measure the flexural strength of glass by proposed experimental procedures. ![]()
