Abstract

ABSTRACT Cho, D., Han, K., 2013. Feasibility Study of Structural Behavior Monitoring with GPS and Accelerometer Coastal structures could be damaged or even collapsed by abnormal ultimate loadings because they are exposed to the extreme natural environmental conditions such as strong winds, earthquakes, and tsunamis, etc. Due to these loadings, they need to be evaluated through a health monitoring continuously. As the displacement of the structures can represent structural behaviors, precise measurement for the displacement of the structures in order to assess reliably the state of the structures is required. In this study, problems of RTK (Real Time Kinematic)-GPS (Global Positioning System) and an accelerometer sensor when applied to structures were experimentally identified through a comparison between results from the experiments. In order to compare the displacements precisely, a steel cantilever beam was fabricated and a variety of displacements by loadings was measured. An integrated displacement wa...
