- Abstract:
- In order to extend service life of concrete structures, realize the sustainable development of concrete structures, save cost and resource, and improve economic benefit during the life cycle, life cycle equal durability design method (LC-EDDM)was proposed based on equal durability design method and life cycle design method, and the core research contents were presented. The basic principle, framework, design process of LC-EDDM were studied. The results show that LC-EDDM is helpful to balance the durability ability, extend the service life and save life cycle cost. The method plays an efficient role in the preliminary design stage in the structural design. Economic benefits can be got if LC-EDDM is applied to concrete structures with high costs and long service lives, such as bridges.
