Determine the number of testing N large enough when calculating the reliability of the construction works according to the step-by-step statistical modeling method

Abstract

The calculation of construction works according to the method of reliability requires a large amount of information about the characteristic parameters of structure, of the ground, backfill, and load. However, the current design standards regulate a limited number of test samples, which do not fully reflect the nature of the quantity being tested, which greatly affects the accuracy of construction calculated results. Therefore, there needs to be a solution to overcome the above situation. In the article, astep-by-step statistical modeling method is presented to calculate the reliability of the construction with the determination of the necessary number of tests N, which is considered large enough and illustrate by calculating the reliability of tipping stability of some particular construction works such as retaining wall. The calculation results show that the simulation method creates a basis for calculating reliability and is an effective tool with high accuracy in calculating and designing construction works.
