Proceeding of the Joint International Symposium on Deformatuon Monitoring. 2-4 November, 2011. Hong Kong. China. Report. The use of GNSS sensors in structural health monitoring has been increasingly important. Technology has advanced far enough that structural parameters can be obtained without the need for accelerometers. This paper discusses the design of a structural health monitoring system where the main structural parameters will be gathered from GNSS sensors employed in a building currently under construction. The structural health monitoring system will be employed in-construction and post-construction and uses 7 tiltmeters and 8 GNSS sensors. The system will be operational for 12 months and will eventually be used to infer the influence of non-structural members on the structural strength.
