For steel structures, two major limit states need to be considered for general design: the ultimate limit state and the serviceability limit state. There are other limit states that may need special treatment and are usually classified under “accidental loadings” in design codes.

Serviceability limit states (SLS) Eurocode 2 part 1-1 gives a general basis for the design of structures in plain, reinforced and prestressed concrete made with normal and lightweight aggregates together with specific rules for buildings. For this part, we have: 48 applications. In the structural design process normally two limit states are considered: ultimate limit state respectively serviceability limit state. In many design situations, particularly in systems like houses and medium sized commercial buildings, acceptable performance of a structural system is seldom defined by ultimate limit states but rather by serviceability requirements.

Serviceability limit states are conditions in which the functions of a building are disrupted because of local minor damage to or deterioration of building components or because of occupant discomfort.^'^'^^ Many serviceabil­ ity limit-states are the result of excessive structural defor­ mations or motions.

What is limit state of serviceability ? A structure should be serviceable and its important that it should serve the intended function throughout its life. When we follow the limit state of serviceability as per Indian Standards (IS 456: 2000), it is ensured that the comfort of people and aesthetic appearance of the structure is satisfactory.

• Design values. • The characteristic value of a material parameter will in general be a 5%  Serviceability Limit States (SLS) Serviceability limit states are states which correspond to conditions beyond which specified service conditions of a structure or structural member are no longer met. Serviceability limit states may be reversible or irreversible. They generally include issues like deformation, cracking and vibration which: Verification of serviceability limit state (SLS) Returning to the example of Figure 2.7, if the maximum settlement that the gantry can tolerate is sCd = 15 mm and the calculated settlement under the design actions is sEd = 12 mm, then the serviceability limit state is avoided, since: Limit state design requires the structure to satisfy two principal criteria: the ultimate limit state (ULS) and the serviceability limit state (SLS).
