Mühendislik yapıları beklenen hizmet ve yaşam süreleri boyunca maruz kalacakları olası yükleri karşılayabilecek şekilde tasarlanır ve inşa edilirler. Kule, gökdelen vb. yüksek yapıların tasarımında, az katlı yapıların aksine, yapıya dinamik yük olarak etkiyen depremin yanısıra, rüzgar yüklerinin de göz önüne alınması gereklidir. Yapıların rüzgar yükü karşısındaki davranışlarının farklı özelliklere sahip sensörlerle izlenmesi, yapı sağlıklarının emniyetlerinin değerlendirilmesi, proje kabullerinin kontrol ve kalibrasyonu yanında, gelecek projelere ışık tutan değerli bir veri alt yapısı oluştururlar. Bu çalışmada, çok katlı betonarme yüksek bir yapının GPS ve eğim sensörü ile rüzgar tepkilerinin eş zamanlı izlenmesi, yapının doğal frekanslarının belirlenmesi ve her iki sensörün yapının dinamik davranışlarını yakalama kabiliyetleri açısından değerlendirilmesi karşılaştırmalı bir yaklaşımla ele alınmıştır

Full-Scale Monitoring of Wind-Induced Response of a Tall Building with Various Sensors and Preliminary Analysis Results Regarding Sensor Integration

Full-Scale Monitoring of Wind-Induced Response of a Tall Building with Various Sensors and Preliminary Analysis Results Regarding Sensor IntegrationThe engineering structures are designed and constructed to be able resist against possible load that could be anticipated during expected service and lifetime. Unlike low-rise building, it is necessary to take into account wind loading as much as seismic load as a dynamic load for high-rise structures in design stage. The monitoring of behaviour of the structures under wind load using sensors which has different ability provide future projects good and valuable information database as well as evaluating of stuctural health and control and calibration of project parameters accepted. In this study, it is dealt with the monitoring of wind-induced response of a multistory reinforced concrete building using GPS and inclination sensor together, determining the natural frequency of the building and evaluating of both sensor in terms of capturing dynamic components of the building with comparative approach
