| Popis: | Concrete fatigue presents probabilistic behaviour evidenced by the wide scatter of cycles to failure under the same conditions. Experimentally-fitted probabilistic distributions have an error in terms of fatigue life that depends on the number of tests. Through statistical resampling, this relationship has been obtained for the Weibull probabilistic distribution fitted to a set of 100 tests and with two additional parameter combinations. Results for low to high cycle fatigue help to obtain design fatigue probability curves or the necessary number of tests for a given admissible error. Their applicability extends to any other phenomenon that follows the Weibull distribution with similar parameters. |
