Structures deform as they experience load, resulting in stress developing within the body of the structure. These deformations, and consequently stresses, can be monitored to ensure that they do not exceed specified limits adopted during design, i.e. serviceability limit state and ultimate limit state. CSI offers different Structural Health Monitoring methods to suit the client needs, such as:
CSI offers flexible timeframes for Structural Health Monitoring; it can be done as a one-off during test day, continuously for a specific duration (days, weeks, months), or periodically/seasonally for example to gauge the different environmental effect during summer/winter to the expansion and contraction of steel railway structure.
Clients/engineers are most likely concerned if there are cracks in RC floor, beam, column, or wall especially if the structure is relatively new and has only experienced the service load it is designed for. They will want to ensure that these cracks do not widen beyond the limit imposed during design. Other times, an engineer might be interested in the existing stress within old pre-stress elements, such as within a hollow core or flat slab units, to ensure they are sufficient in capacity to support additional loading.
Vibration monitoring is useful for researchers as well as for practicing engineers.
