“…In the traditional bridge management system (BMS), the required information regarding the condition assessment, maintenance activities, and inspection reports are stored in the BMS database. Such information is utilized to assist in the prioritization of bridge maintenance and selecting the optimal strategy plan [7]. The prioritization of bridges for maintenance also involves setting evaluation criteria to rate the bridges to obtain a total score for each bridge in the network under consideration.…”

This paper introduces a newly developed decision support model for allocating a budget for bridge maintenance. The model is built based on capturing the experts’ knowledge for the prioritization of criteria for selecting a bridge maintenance plan. A literature review and interviews with a group of nine local experts were carried out to identify the criteria for bridge prioritization for maintenance. A questionnaire survey was then designed and administered, utilizing multi-criteria decision-making techniques through face-to-face meetings with local bridge maintenance managers to determine the weights of the identified criteria and develop the utility curves for each criterion. The developed model consists of four major modules: (1) bridge ranking module; (2) prioritization module of bridge structural elements; (3) optimization-based simulation module; and (4) the outputs module. The model was validated in a hypothetical network of four bridges. The validation reveals that the model can assist bridge maintenance managers in setting a bridge maintenance plan, with a high level of confidence using efficient frontier analysis technique. Utilizing frontier analysis enables comparisons of mean costs of different bridge maintenance plans against different levels of risk to enable decision-makers to make informed decisions. The result of this study indicated that bridge structural condition was the most important criterion amongst all the criteria influencing the decision of bridge prioritization for maintenance, followed by traffic and bridge location. Moreover, bridge deck and parapet, followed by bearing pads, were found to be the most important of the bridge’s structural elements.

The paper considers the reasons for reducing the load-bearing capacity of bridge structures. Factors affecting the feasibility of major bridge repairs are identified and some ways of their implementation are analyzed. An improvement of one of the modern methods of repairing bridge beams – pasting them with carbon lamellas is proposed. The improvement essence is the use of a device for tensioning reinforcing belts and the proposal to use carbon fiber lamellas as puffs, similar to Sprengel puffs. The method consists in stretching the lamella along the lower edge of the beam edge and fixing it using the developed anchor, not by gluing.
