A Feasibility Study of Building Structural Deformation Monitoring Essay

A Feasibility Study of Building Structural twisting monitor using Global Positioning (GPS) - Essay ExampleTo achieve their objectives through this study, the authors monitored structural deformations in one high-rise building, viz. the Twin Tower of erudition and Technology Complex, and one low-rise building, viz. the Innovation Centre Building, both of which belonged to the University Technology MARA (UiTM), in Selangor, Malaysia. The authors chose high accuracy GPS (1 mm) and total target ( 1 mm, 1) to apply in deformation monitoring of the buildings, to improve accuracy of the adopt. During the course of the study, authors identified appropriate points on the building structure, and suitable assert points around the building to begin the structural monitoring process. They then carried out GPS surveys using the rapid static technique, geotechnical surveys through crack-width measurements using the digital movement adjudicate, and world(a) surveys using the intersection tech nique on the building structures for four epochs. In this study, the authors demonstrated that while crack width measurements using the digital movement gauge were helpful in identifying deformations occurring in one dimension (1 D), the intersection technique of terrestrial surveying is advantageous for monitoring the deformations that occur in two dimensions (2 D). However, the GPS survey was of no utility for monitoring the building deformations, as it did not provide consistent results. According to the authors, the inconsistency of results of the GPS survey was due to obstruction of the antenna that was to secure the satellite signal, by the surrounding building structures. The strength of this study lies in the fact that accuracy in survey methodological analysis and results was maintained. The authors successfully demonstrated the utilise of miscellaneous survey techniques in monitoring building structure deformation through appropriate and reliable data and measurements. The information on the efficiency of the various techniques in monitoring building structure deformation occurring in 1D and 2D will prove to be useful in choosing the appropriate technique ground on individual building survey requirements. The weakness of this study, however, is that it suffers from lack of appropriate data analysis, as the objective, i.e. assessment of the advantages and disadvantages of the discussed techniques was not sufficiently met. Importance of the study This hold is significant as the authors assess the most prominent survey techniques and distinguish them based on their utility in deformation monitoring. The study will change making a better a choice while choosing which type of survey technique is to be used when deformations occurring in 1D or 2D ar to be monitored. This study also indicates that using GPS for monitoring deformations is futile in areas where surrounding high-rise buildings and obstructions exist, such as in cities. This paper provid es concise methodology and distinct deformation monitoring techniques that will be helpful in carrying out deformation measurements for my project study. 2. Deformation Monitoring by GPS at Embankment Dams and Deformation Analysis Summary The main objective of this study was to assess deformation at the crest of the Altinkaya dam up, caused by a combined effect of the weight of the dam and the water load occurring at different water levels. A secondary objective was to investigate if GPS surveying technique and its measurements are accurate enough to be used for examining deformations
