Abstract. This article provides an analysis of existing methods for determining the carrying capacity of bridges and ways of improving them. The authors propose a modernization of the technology assessment capacity long maintained bridges with the use of mobile automated monitoring systems installed for a certain period of time (from 1 to 6 months). This system will allow to record the reaction of various structural members of the bridge to traffic loads and the impact of geodynamic and climatic nature, as well as to predict and warn about the likely development of hazardous processes and, thus, provides for timely preventive safety and economic efficiency of operation of transport facilities. On the basis of data of mobile automated monitoring systems are determined by the coefficient of variation of operation of the computational model from the actual operation of the structures, which clarifies the capacity of the bridge. The technology used will clarify the calculation models of the bridge relative to the actual spatial and non-linear operation of its structures, to evaluate the carrying capacity of the bridge with a full complement of functional load factors, loading and environmental influences. The authors formulated the main provisions of the mobile automated system monitoring and the proposed scheme assessment of load capacity using this system.

Keywords: bridges; assessment of carrying capacity of bridges; monitoring system; constructive factor; account of external influences; numerical modeling; nonlinearity of the system
