Abstract

Recently, the method of structural response analysis using a limited amount of multi-response data (SRALMR) that can estimate global structural responses was developed and verified with numerical analysis models. As a next step of the validation using the numerical analysis model, a prototype of monitoring system for global structural response (PMS-GSR) was established using wireless sensor network and SRALMR in this study. In addition, the graphical user interface was constructed for estimation performance analysis and user convenience. The experimental validation of PMS-GSR was conducted for beam structure under four load cases (LCs) and sensor-layout cases (SLCs). The experimental specimens were 2-span and 3-span beams, and a wireless sensor network including displacement, slope, and strain sensors was used. Finally, the global displacement, slope, and strain were estimated using PMS-GSR, and estimated global responses were analyzed according to the LCs and SLCs.
