Simple Techniques to Analyze Vibration Records from Buildings

Abstract : In parallel to rapid developments in recording, sensor, and communication technologies, the number of structures installed with vibration monitoring systems is increasing rapidly all over the world. The scientific field dealing with the analyses of structural monitoring data is known as System Identification, and involves a large number of advanced techniques requiring expertise and background for usage. Since analysis of digital data is typically not covered in standart structural engineering curriculum, a large amount of data from monitored structures are not being analyzed properly and correctly. This paper shows that there are simple techniques to analyze vibration data from structures. For building-type structures, it is possible to identify basic dynamic characteristics of a structure by using only Fourier transforms and band-pass filters. We show that, by using these two tools, we can identify modal frequencies and damping ratios, mode shapes, interstory drifts, torsional vibrations, rocking vibrations, and soil-structure interaction.
