摘要：
A multi-attribute decision making method considering sustainability for the design and maintenance of reinforced concrete (RC) structures in chloride environment was proposed to effectively prolong the service life of major engineering structures and reduce their adverse effects on the environment and society. The proposed method can solve the problem of inconsistent ranking of different attributes in engineering decisions, and provide decision indicators and ranking methods that comprehensively consider sustainability for decision makers with different risk attitudes. In this method, the performance evaluation module, the cost analysis module, and the utility analysis module were established. The long-term performance deterioration, improvement effect and maintenance timing of various maintenance measures (including epoxy coating, bidirectional electromigration, strengthening with bonded steel plate and carbon fiber reinforced polymer (CFRP)), life-cycle sustainability cost and its uncertainty were sequentially analyzed. Furthermore, the weights of economic, environmental and social costs were determined by the combined weighting method, and the multi-attribute utility values of different design and maintenance schemes were calculated for decision making. A case study of RC box girder with a design service life of 200 years was conducted. Result indicates that the long-life schemes designed to improve structural performance, reduce the risk of failure, and reduce the number of maintenances are more sustainable, but the combined utilities of the different types of costs and performance improvements need to be weighed. © 2023 Zhejiang University.
