“…Until recently, numerous studies have been conducted concerning the technical feasibility of using DGPS to measure dynamic displacements of high-rise buildings and tall slender structures (Çelebi 2000;Tamura et al 2002;Kijewski-Correa et al 2006;Li et al 2006;Breuer et al 2008;Park et al 2008;Yigit et al 2010;Pehlivan et al 2013;Yi et al 2013), long-span suspension and cable-stayed bridges (Nakamura 2000;Xu et al 2002;Roberts et al 2004;Erdo gan et al 2007;Meng et al 2007;Yi et al 2013a), and short-span bridges (Moschas & Stiros 2011Psimoulis & Stiros 2013). Literature reviews on the application of GPS-based monitoring for high-rise structures and for SHM are available (Im et al 2013;Yi et al 2013b).…”

Monitoring the response of engineering structures, such as tall buildings, tower and large-scale bridges, under severe loading conditions, such as strong earthquake or wind storm, is an important requirement to verify their design and construction and to evaluate structural condition and reliability. In the last two decades, high-rate real-time or post-processed kinematic differential Global Positioning System (DGPS) has been widely used in dynamic displacement measurements of civil engineering structures. In recent years, interest has increased for Precise Point Positioning (PPP) due to its capability to generate positioning solutions as accurate as DGPS. In this study, the potential of postprocessed kinematic PPP in terms of monitoring dynamic displacement response of a structure has been explored based on free damped oscillation events obtained from a model structure, which is able to vibrate in the fundamental and higher modes of vibration. A number of experiments have been carried out and five events, each of which is different character, have been selected to compare PPP results with DPGS results in the time and frequency domain. The results clearly demonstrate that the PPP method, like the DGPS method, offers great potential for the measurement of horizontal and vertical dynamic movement of structures. The impact of a short period (one minute) of observation length on the result of the kinematic PPP method was also investigated in terms of sensing the dynamic movement of a structure. Twenty selected one-minute data-sets extracted from a one-hour original data-set were processed by Canadian spatial reference system PPP and each one-minute PPP solution was compared with the corresponding segment obtained from the one-hour PPP solution. The results show that the oneminute PPP solution is able to extract the fundamental natural frequency of the oscillation in the horizontal and vertical component just like the one-hour PPP solution after the offset is removed and the lower frequency trend component is filtered out.

“…Such sensors include the linear variable differential transformer (LVDT) (Park et al 2005), laser-Doppler vibrometer (LDV) (Nassif et al 2005;Lee and Park 2011;Choi et al 2013), global positioning system (GPS) (Loves et al 1995;Nakamura 2000;Celebi 2000;Tamura et al 2002;Breur et al 2002;Kijewski and Kareem 2003;Park et al 2008;Kaloop and Li, 2014;Yi et al 2014), and vision-based monitoring (Coronado et al 2012). LVDT and LDV are 1D sensors that measure displacements along the direction of an axis.…”
