| Title of the article | Estimation durability of steel constructional elements of highway bridge on basis of statistical simulation method |
| Abstract. | To estimate the endurance of steel elements of bridges and their compounds requires information allowing to consider the variability of rate and intensity of movable load, its relative location in the column, and the bands (multilane in motion) as well as other relevant factors. As the analysis of the results of various scientific studies in the field of bridge construction, as well as work in related fields of science, has accumulated a rich statistical material that requires a systematic and, to some extent, of verification. This paper presents a framework for an improved methodology for assessing and forecasting the estimated endurance of steel structure elements of highway bridges based on a combination of the reliability theory and mathematical statistics, methods of structural mechanics and risk management. The difference between the proposed evaluation system is used in the calculations that the statistical distribution functions characteristic factor , and the transition from the initial to intermediate and final parameters is based on deterministic functions interaction between these factors and algorithms for numerical sets obtained by a simulation of basic processes. At the heart of obtaining analytical expressions for the description of random processes of change over time calculation parameters laid receiving confidential approximation of sets of numbers developed by the author. The paper discusses the practical examples of developed regulations for an improved system of procedures for the formation of an adequate statistical model of traffic flow and estimate the number of estimated impacts on the structural elements of the bridge on the basis of studying the characteristics and location of the destination facilities and procedures for the selection of design schemes uploading time load. Found that the simulation experiments based on a combination of rational methods of reliability theory and mathematical statistics, methods of structural mechanics and risk management, in conjunction with the objective data of automated traffic control, permit, with a given reliability, perform a prediction of random processes in the «artificial construction – Wednesday manual – processes of degradation». |
