摘要: |
Sustainability is a key issue which must be addressed in the design, construction and lifelong maintenance of civil engineering structures. This lecture will look at sustainability in relation to bridges. Motorway bridges built in the 1960s and 70s had design lives of 120 years; however many showed signs of deterioration after only 20-40 years. This led to much debate on the issue of initial versus full life cycle costing which is still ongoing today. To address the highly complex issue of the sustainability of bridges, the author will discuss a number of specific areas: The use of innovative in-situ testing equipment to assess the long term durability of concrete Designs which allow repairs to be carried out on a bridge whilst it is in use Innovative structural designs which will extend service life at minimal additional cost |
