Investigation of structural health monitoring of a high rise building ; Yüksek katlı bir binanın yapısal sağlık izlemesinin incelenmesi
High-rise buildings must be designed bearing in mind the possibility of an earthquake in earthquake-prone megacities such as Istanbul. Additionally, the health of the existing high-rise buildings must be constantly controlled before, during, and after an expected earthquake. The structural health monitoring system is used to observe the dynamic conditions of existing structures and their behavior during the earthquake. In addition to system identification techniques, structures can also be examined through their mathematical models. Therefore, the models of the existing structures need to including existing masonry infill walls and soil-structure interaction, which influence the real behavior of the structures. The main aim of this thesis is to build a correlation between dynamic properties from on-site measurements and finite element analysis of the high-rise building by correcting the FE model of the building based on the investigation of SHM of the building. For this purpose, the study was carried out on a high-rise building in Fikirtepe, Istanbul. A system to monitor the building for twenty-four hours a day over seven days was installed. Moreover, the finite element model of the building is modeled with the package program, ETABS v16.0.0. The study was conducted on the response of the building during the earthquake that struck southwest of Istanbul in the Marmara sea, Silivri deficits, on Sept 26, 2019. Ambient vibration records of the building are examined by the frequency domain decomposition. With the method, the natural periods and mode shapes of the building are obtained. As a result of the analysis carried out before and after the earthquake, it is found that the building has a linear behavior during the earthquake. Additionally, the response of the building during the earthquake is investigated through acceleration-time history. The transfer functions are obtained by using Fourier Transform and power spectral density method. The predominant period, model shapes, and damping ratio are calculated ...
