ASSESSMENT OF BRIDGE RELIABILITY IN UKRAINE
Abstract
ntroduction. The strength of the structure can be ensured in the case when the acting forces are less than the resistance of the element. In order to exclude the possibility of destruction, the resistance of the elements was artificially reduced, forming certain reserves. This method is called the allowable stress method. This method was used all over the world, and until recently the USA and Japan. Such reduction of stresses was performed more on experience than on the basis of mathematical calculations. Problem statement. The article provides a brief description of the principles of evaluation of structures reliability. It had been described as calculated characteristic and design loadings. It is shown that there is now a balance between the loadings in EN 1991-2 and in DBN B.1.2-15:2009. Purpose. The article is devoted to the problem of evaluation of the reliability of Ukrainian bridges, which are designed according to national standards.
