Application of a Quality Control Plans on a Truss Bridge

Abstract

Infrastructure is vital to the prosperity and welfare of the citizens of a country. In order to take full advantage of its benefits to the society it is necessary to manage these valuable resources in a proper manner. A sophisticated computerized bridge management system (BMS) is a means for managing bridges throughout design, construction, operation and maintenance of bridges. Throughout Europe there are different management systems developed and adopted to the local requirements and needs, which may lead to different decisions on maintenance actions. In order to overcome this issue a COST Action TU 1406 has proposed a guideline for standardization and development of quality control plans for roadway bridges. In order to perform such analysis, first of all it is necessary to collect available data, conduct element identification and grouping, define vulnerable zones, damage processes and failure modes. This is followed by selection and evaluation of the performance indicators (PIs), calculation of key performance indicators (KPIs), establishing demands, and finally creating Quality Control Plan (QCP) scenarios and comparing them by spider diagrams. In this paper an example of the proposed procedure will be shown on a steel truss bridge in Israel.
