“…The fitted curves agree well with the amplitude and phase of the wavelet skeleton, and the fit for the natural frequency appears to be better than that for the damping ratio. This observation is consistent with results from other full-scale monitoring programs (Bashor et al, 2012).…”

“…A large number of full-scale measurements on the wind velocity, wind pressure, and wind-induced response have been conducted for studying the wind effects on high-rise buildings or bridges (e.g., Tamura et al, 2002;Satake et al, 2003;Macdonald and Daniell, 2005;Li et al, 2007;Fu et al, 2008;Wang et al, 2010;Chen et al, 2011b;Bashor et al, 2012;Chen et al, 2013). These measurements have greatly enriched our knowledge of natural winds in terms of wind spectrum, turbulence intensity, and enhanced our understanding of dynamic properties of fullscale structures in terms of the modal parameters.…”

“…Large aerodynamic loads act on the building structure which makes the building vibrate in rectilinear and torsional modes, as discussed in [41] . Full scale monitoring was carried out in [42] to better understand the methodology used to predict the acceleration response of high-rise buildings consistent with on-site behaviour. A full scale monitoring programme has been discussed in [43,44] .…”

(2018) Modelling and simulation of a stationary high-rise elevator system to predict the dynamic interactions between its components. International Journal of Mechanical Sciences. 137, It is advisable to refer to the publisher's version if you intend to cite from this work. In a high-rise elevator system lateral vibrations of the suspension and compensating ropes, coupled with vertical motions of the car and counterweight are induced by the building structure motions. When the frequency of the building coincides with the fundamental natural frequency of the ropes, large resonance whirling motions of the ropes result. This phenomenon leads to impacts of the ropes on the elevator walls, large displacements of the car and counterweight making the building and elevator system unsafe. This paper presents a comprehensive mathematical model of a high-rise elevator system taking into account the combined lateral stiffness of the roller guides and guide rails. The results and analysis presented in the paper demonstrate frequency curve veering phenomena and a wide range of resonances that occur in the system. A case study is presented when the car is parked at a landing level where the fundamental natural frequencies of the car, suspension and compensating rope system coincide with one of the natural frequencies of the high-rise building. The results show a range of nonlinear dynamic interactions between the components of the elevator system that play a significant role in the operation of the entire installation.Crown

“…In the Chicago Full-Scale Monitoring Program [9], the dynamic response of 3 tall buildings has been monitored over a decade to study the amplitude dependency of the damping. Furthermore higher damping levels are observed at structural systems with a greater degree of frame action than cantilever action.…”

Abstract. In this paper, a damping model for a high-rise building is introduced. This model is used to investigate the possibilities to identify the relative damping contribution of the internal material damping in building elements, energy loss at element interfaces and energy outflow at the interface with the ground. The building is modeled as an Euler-Bernoulli beam which is elastically supported at its base by a translational and rotation spring, including viscous damping elements. The beam has internal viscous material damping and is attached to a distributed viscous damper. Data obtained from conventional full scale measurements of the vibrations at the top of a high-rise building
