Identification of the Dynamic Properties of the Residential Tower New Orleans

This paper describes the application of the Frequency Domain Decomposition (FDD) technique on measured acceleration data on the residential tower New Orleans in Rotterdam, the Netherlands. The goal of this study is to determine and analyse multiple natural frequencies and mode shapes of this tower. A measurement campaign was setup on the 158 m...

High-rise structural property identification

Wind-induced vibrations are an important aspect in high-rise building design. The structural properties that influence vibrations are the mass and stiffness of the building and the foundation. These properties are difficult to predict in the design, resulting in inaccurate predictions of the dynamic response. As a first step towards better...

Monitoring of wind-induced vibrations on a 215 meter tall residential building

Comparison between in-situ measurements and design values of high rise dynamic characteristics shows that current way of predicting these values is inaccurate. The HiViBe project aims to develop models which provide for more reliable predictions of the dynamic characteristics and response of high-rise buildings. To that end, measurements are...

Vibration Threshold Exceedances in the Groningen Building Vibration Monitoring Network

Vibration assessment criteria for cosmetic building damage are specified in terms of peak velocity thresholds. For masonry buildings, these thresholds are relatively low compared to vibration levels generated by various sources in the built environment. Therefore they will be exceeded numerous times over the lifetime of most buildings. These...

Characterization of vibrations measured in the Groningen building monitoring network

A study was undertaken to define which set of signal characteristics can be used to differentiate between various vibration sources in a built environment. Several datasets of vibration measurements on known sources are obtained and analyzed. A set of 11 signal characteristics were determined for all signals. Based on the correlation between...

Analysis of the Cabauw tower response under wind gust events

In the period between May 2019 and May 2020, the movements of the Cabauw observational tower have been monitored. This monitoring campaign was set up to monitor the behaviour of the tower before (period 1), during (period 2) and after (period 3) replacement of the stay cables. The observations during these periods have been reported in TNO...

Monitoring vibrations of the KNMI Cabauw observation tower

Since 1970, KNMI operates a 200 m tall observational tower near Cabauw, in the centre of the Netherlands. The tower consists of a steel tube, which is guided at four heights, with guides in three directions. Observations of the vibrations are done on several heights. For this purpose, the tower includes observation decks and outriggers for...
