A performance-based design methodology is applied to a prestressed concrete continuous bridge with quantifiable assessment of life-cycle cost and CO2 emissions, accounting for durability, normal use and seismic risks. The reference structure was originally designed using traditional total- prestressed criteria. In this paper, the benefits of partially-prestressed concrete are investigated through a Life-Cycle Analysis of cost and environmental impact. In order to assess the durability deterioration risk, two different climate scenarios are investigated, representing the current situation and a plausible climate change worsening. The results of the Life-Cycle Analysis are compared in order to derive recommendations for practical applications of performance-based design for improved sustainability performance and conclusions are drawn. |
