As an important parameter,bridge design life including design life of the bridge and design life of the component,which will determine durability measures and maintenance works and life cycle cost over the bridge lifetime.To get a rational design life of a component,four issues should be solved: (1) What are the critical factors that influence the design life of a bridge component? (2) How to deteriorate during the lifetime of a component? (3) When does a component reach the unaccepted performance level? (4) Which solution is the optimal one?
