• Serviceability Limit State (USL) The ULS is a condition of the structure which, if exceeded, immediately leads to a mathematical collapse or other form of failure. The SLS is a condition of the structure which, if exceeded, no longer fulfils the conditions specified for its use, without a loss of bearing capacity. For geotech- nical constructions, the SLS includes the ser-viceability of

Two basic limit states are defined by AS/NZS 1170 Structural design actions – the serviceability limit state (SLS) and the ultimate limit state (ULS). Serviceability limit state (SLS) The SLS represents a level of stress or strain within the building below which there is a high expectation the building can continue to be used as originally intended without repair.

Serviceability limit state design of structures includes factors such as durability, overall stability, fire resistance, deflection, cracking and excessive vibration. For example, a skyscraper could sway severely and cause the occupants to be sick (much like sea-sickness ), yet be perfectly sound structurally.
This paper reviews and discusses the serviceability limitations inherent in current design codes and guidelines in terms of stress limitation, cracking and deflection control.

there is also a table of suggested serviceability Limit state Criteria in as/nZs1170.0:2002 table C1, however it should be emphasised that these limits are a guide and the designer should exercise engineering judgement.
In the AASHTO LRFD Bridge Design Specifications, a limit state is defined as “a condition beyond which the bridge or component ceases to satisfy the provisions for which it was designed.” Bridges designed using the limit-states philosophy of the LRFD Specifications must satisfy “specified limit states to achieve the objectives of constructability, safety and serviceability.” These

3.1 Serviceability limit state The serviceability limit state defines what constitutes a serviceability failure. In the present paper serviceability non-compliance is deemed to occur when a deflection exceeds an allowable deflec-tion limit as a result of flexure. Since the deflection model of the structural steel member is based on elastic behavior, the maximum deflection of a simply supported
