ABSTRACT
The design life of bridges is conventionally set to 100 years [5.1]. During this life, the bridge has to comply with certain basic requirements that refer to structural resistance, serviceability, and durability and are met by appropriate design, production, execution, and use. Concerning the design, this is based on consideration of ultimate and serviceability limit states (SLSs) that have to be verified for persistent, transient, and accidental design situations.
