Abstract
Compliance criteria for the sample size n = 3 have a lot of disadvantages [5,6,7] and they can affect the reduction of quality of produced concrete and, consequently, they can cause too much risk of the recipient (the investor) side. Therefore, the effect of the sample size on the defined quality index of produced concrete has been evaluated. The effect of the sample size and standard deviation on the reliability index of reinforced concrete structures has also been determined.The impact analysis of compliance criteria on the reliability index of reinforced concrete structures was conducted for a compression column. The obtained values of the reliability index results confirm the correctness of the quality index formula and concrete quality proposed in method of defining.
