Lesson plan
Serviceability (structure)
In civil engineering and structural engineering, serviceability refers to the conditions under which a building or road surface is still considered useful or acceptable. Should these limit states be exceeded, a structure that may still be structurally sound would nevertheless be considered unfit. For buildings, it refers to conditions other than the building strength that render them unusable. 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 building is in no danger of collapsing, yet since it is obviously no longer fit for human occupation, it is considered to have exceeded its serviceability limit state.
