ANALYTICAL MODEL EXPERT ASSESSMENT CONDITION OF BRIDGES

The statement of problem, the relevance of the chosen topic, an analysis of latest research, and purpose and tasks of work are outlined. The technical condition of bridge is determined by condition of structural groups of elements. In order to provide a formalized assessment of condition of building as a whole, the expert assessment indicator is used in regulatory documents. This assessment is a generalized characteristic of operational suitability of structure. In previous normative documents, it was proposed to define the expert assessment (expressed in points) according to empirical formulas, which under certain circumstances did not correspond to the specific condition of object (technical operational condition) determined by survey materials. Therefore, it became necessary to change the approach to this problem. In the presentation of the main material of the study, a numerical criterion technical condition of the structure is proposed, which is necessary for a practical method of forecasting operational condition of the bridge. Any building structure consists of a certain number elements, condition of which affects the overall operational condition structure. During survey with the subsequent determination of the expert assessment structure, not only the condition of each element separately, but also impact of each element on the general condition of structure as a whole should be taken into account. For this, normalized influence coefficients are used, which, depending on the importance of each element, can change and acquire values in the range from 0 to 1, which will subsequently affect overall evaluation of the structure. These weighting coefficients of influence in the work are determined by the method of analysis of hierarchies. A new rating evaluation formula is proposed, results of the work are summarized, and prospects for further research in this direction are outlined. The proposed definition of expert evaluation is mathematically justified and can be generalized for the definition of expert evaluation other building structures. Using method of hierarchies, other normalized influence coefficients can also be calculated. This will make it possible to significantly expand the capabilities of expert for decision-making regarding the implementation of operational activities and types of repairs
