Bridge quality appraisal methodology: application in a reinforced concrete overpass roadway bridge
Artikel i vetenskaplig tidskrift, 2018
Bridge quality control plans and asset management systems are often integrated in collective frameworks used by authorities
nationally and internationally. Similarities among these frameworks include the utilization of performance indicators for quality appraisal.
However, there are discrepancies in the ways such frameworks are researched, developed, and applied. Additionally, there are problematic
aspects even in their common characteristics, like the relative absence of correlation between observed performance indicator values
and benchmarked ones, and the deliverables’ disparity due to the diversity of the quantified indicator variables. For the alleviation of such
problematic aspects, this paper presents a bridge quality appraisal methodological and computational framework. It builds on (1) the adaptation
of the sustainable building methodology and its combination with expert input solicitation methods and the research findings of
the European Cooperation in Science & Technology (COST) Action TU1406, and (2) a multi-input adaptation of the analytical hierarchy
process. The methodology is presented in terms of its general procedural steps and calculating requirements, and then it is tailored to
reinforced concrete overpass roadway bridges. The methodology’s application in a real case study concludes the presented research.
