ABSTRACT

vehicle is an extremely important and difficult task; for which it requires very accurate and effiCient calculation and consideratio

due to a limited budget This project focuses on Multi Element Bridge Management System (ME - BMS) research and applieati

in the maintenance and repairation plan for a practical case in particular The objective is to support different management level

in establishing a maintenance and repairation plan in which financial constraints and bridge quality requirements after repairatio

ement and the whole network will be determined annually At the same time, this project also helps to define the element conditi

rating (ECR) and network condition rating (NCR) before and after repairation
