WebbAs discussed in Chapter 3, limit states are usually classified into four types: Serviceability limit states (SLS) that represent criteria governing normal functional or operational use. Ultimate limit states (ULS) that represent the failure of the structure and its components usually when subjected to extreme values of actions or action effects. http://bridgedesign.org.uk/tutorial/eu-load-combinations.php
