| Title of the article | Evaluation of remaining life of steel structure operated in a corrosion environment |
| Abstract. | General algorithm of steel construction unit operated in a corrosive environment life prediction is developed and tested. Regression analysis software utilities are used for modelling of corrosive wear. Presented in the article the algorithm allows to determine dates of further safety operation and to plan capital repair of buildings and constructions structures. With a view to solve multiparameter question of life prediction the successive formation of initial parameter by the most significant characteristic, which is described by the six general steps, used. In this case, correcting of design parameter number depending on the calculation task, engineering system criticality and required level of evaluation reliability seems possible. Performed procedures demonstrativeness achieved by using PC classical design products that are at the command of engineer, for example, by using MathCAD multifunctional system. In addition, the article shows, that the presented algorithm allows choosing most convenient regression model. This fact is so much important, especially when accounting task of actual degradation of each element of rated section is stated, that by the best way provides an approximation of structural model according to the real work of technical system. Presented in the article life prediction procedures describes at the example of real technical system, monitoring of the state of that was organized by the specialized organization, that shows practical significance of stated recommendations. |
