Health monitoring of buildings during construction and service stages using vibration characteristics
Moragaspitiya, Praveen, Thambiratnam, David, Perera, Nimal, & Chan, Tommy H.T. (2012) Health monitoring of buildings during construction and service stages using vibration characteristics. Advances in Structural Engineering, 15(5), pp. 717-726.
Columns and walls in buildings are subjected to a number of load increments during the construction and service stages. The combination of these load increments and poor quality construction can cause defects in these structural components. In addition, defects can also occur due to accidental or deliberate actions by users of the building during construction and service stages. Such defects should be detected early so that remedial measures can be taken to improve life time serviceability and performance of the building. This paper uses micro and macro model upgrading methods during construction and service stages of a building based on the mass and stiffness changes to develop a comprehensive procedure for locating and detecting defects in columns and walls of buildings. Capabilities of the procedure are illustrated through examples.
