Evaluation of resilience of bridge engineering system under earthquake disaster
In order to ensure the safety of bridge construction and improve the anti-seismic defense capability of bridge construction, based on the concept and characteristics of toughness theory, the toughness evaluation of the bridge is carried out. In this paper, starting from the three attributes of disturbance force, absorption force and resilience, considering the characteristics of bridge construction, safety management, emergency measures, etc., a bridge seismic safety and toughness evaluation index system containing 22 indicators is determined. Take G1-Entropy Weight Method (EW) as the composite weight and construct a single index measurement function. Finally, the set pair analysis is introduced into the unascertained measure theory. Use this model to determine the toughness grade of the bridge and verify the rationality and feasibility of the model through examples. Providing a new way of thinking for bridge seismic toughness assessment.
