| Résumé : |
Structural Health Monitoring (SHM) plays a critical role in ensuring the safety and func-
tionality of vital structures such as bridges, dams, and public buildings. To make SHM sys-
tems more cost-effective, it is essential to optimize the number and placement of sensors,
reducing implementation costs while maintaining reliable damage detection and structural
assessment.
This study addresses the problem of optimizing damage-adaptive sensor layout in struc-
tural health monitoring (SHM) for multi-story buildings. A three-dimensional finite ele-
ment model of a 12-story reinforced concrete tower (R+12) was developed using SAP2000,
enabling the identification of high-risk damage zones based on internal force distributions.
Steady-state vibration responses were generated, and a genetic algorithm was used to iden-
tify the optimal sensor configuration for each damage scenario using distance matrices as
damage-sensitive features. These scenario-based layouts were then merged into a unified
configuration by analyzing sensor occurrence and importance scores. The final sensor
set ensures sufficient coverage and sensitivity to structural degradation while maintaining
a reduced number of sensors. The proposed approach provides a scalable and practical
solution for SHM system design in complex structures with anticipated damage regions. |
