Abstract: This dissertation will present the analysis of displacements and responses of a high-rise structure - Guangzhou New TV Tower under service loading conditions and temperature changes. It is an important requirement for the validation of the design and for the assessment of structural safety and serviceability. GPS can measure directly the position coordinates, hence providing an opportunity to monitor, in full scale, the displacement and dynamic response of the structure to which the GPS antennas are attached. It allows the researchers to examine the theoretical assumptions made during the structural design. With the use of the GPS, the engineers are able to check the correctness of the design and ensure the stability of the building. Previous studies have indicated that the use of GPS technology for long-term monitoring of tall civil structures is more beneficial as compared to the use of traditional sensors. This dissertation is to carry out an analysis on the displacements of a high-rise structure under temperature changes, which were measured using GPS technology. The dissertation will particularly address the following issues: (1) Evaluation of the GPS technology and its applications to high-rise structures; (2) Analysis and comparison of the accuracy in measuring vertical and horizontal displacements; (3) Analysis of the real-time kinematic (RTK) GPS for temperature- and wind-induced dynamic displacement monitoring; (4) Implementation of GPS technology for temperature- and wind-induced displacement monitoring of a 610 m high TV tower.
