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.

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
