| description | This article presents the results of reinforcement cover thickness measurements carried out in several buildings erected in 2022 in Rzeszów. The results of the measurements are presented in two variants depending on the reinforcement cover thickness assumed by the designer: the first variant contains all the results and the second contains results only from places where the designed cover thickness was 25 mm. For both variants, a histogram of the percentage deviation from the design value was determined and mean values, standard deviation, coefficient of variation and maximum values of negative and positive deviation were calculated. The obtained reinforcement cover thickness distributions were used to determine the reliability of a floor slab with a simply supported beam static scheme. Analyses were carried out for 4 slabs differing in span, thickness and selected reinforcement. Using the FORM analytical method, values for the reliability index and probability of failure were determined. The reliability index values obtained were compared with the values required by EC 1990 and ISO 2394. The results obtained did not meet the standard requirements. |
