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 become increasingly important. GNSS technology has advanced to the stage where structural parameters can be obtained often without the need for supplementary information from other instrumentation. This paper discusses the design of a structural health monitoring system where the main structural parameters will be gathered from GNSS sensors and tiltmeters installed on a building under construction. This paper also discusses the use of low-cost MEMS accelerometers to complement the GNSS sensors. The structural health monitoring system will be employed in-construction and post-construction and uses 8 GNSS sensors, 7 tiltmeters and several MEMS accelerometers at critical locations. The system will be operational for approximately 12 months. Results from the system will eventually be used to infer the influence of non-structural members on overall structural stiffness.
