Serviceability failure
In engineering, a serviceability failure occurs when a structure does not collapse, but rather fails to meet the required specifications. For example, severe wind may cause an excess of vibration at a pedestrian bridge making it impossible to cross it safely or comfortably; similar execssive vibrations can be caused by pedestrians themselves due to their walking, running, jumping; similarly, storm conditions may cause water to spill over a coastal structure, so that boats are not safe behind the structure).
Examples of serviceability failures include: a) Deformations b) Vibration c) Cracking d) Leakages
