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 predictions, this study aims to obtain accurate values of in-situ structural properties using a parameter identification technique in combination with measured modal characteristics. This study applies the technique to estimate the structural properties of a 150 m high residential tower in the Netherlands. The structural properties that were obtained for the residential tower differ significantly from the original design values.
