Highlights

  • Structural Health Monitoring (SHM) for civil structures involves the use of various sensing devices and ancillary systems to monitor the in situ behaviour of a structure to assess the performance of the structure and evaluate its condition

  • This presentation will report the recent advances in SHM in these three categories

  • The application category includes a number of ongoing projects on developing various Damage Detection (DD) methods, e.g., correlation Modal Strain Energies (MSE) with Multi-Layer Genetic Algorithm (ML-GA) based optimization; a multi-criteria approach using a combination of natural frequencies, Modal Frequencies (MF) and MSE to detect damage in bridges, buildings and dams; a correlation based method using the ratio of geometric MSE and natural frequency (GMSEF); time domain based methods based on Auto-Regressive (AR) and Auto-Regressive Moving Average (ARMA) models; enhanced MF for locating damage in suspension bridge main cables and hangers
