Nachhaltigkeit und Resilienz - Zukünftige Kriterien bei der integrativen Bewertung von Brücken

Sustainability and resilience - Future criteria for the integral assessment of bridges.

The term sustainability is very topical for 10 years in Germany and also for bridges several German assessment approaches are developed for the life-cycle analysis of bridges. Simultaneously the term resilience gains in importance, especially internationally. Resilience covers direct and indirect social impacts in the case of the occurrence of an extreme event (earthquakes, flooding, storms etc.) during the life-cycle of infrastructures. Until now, both concepts have been developed by different research disciplines and often the disciplines do not recognize each other. The analysis of both concepts shows many common issues, e. g. integration of social and economic aspects, inclusion of the complete life-cycle and decision support during the design stage of bridges. The paper introduces both concepts resilience and sustainable development, shows the state of the art and presents common grounds and differences. By means of a numerical example the basis of an integral assessment is illustrated and the criteria to be applied are emphasized.
