Extending the Fixed-Points Technique for Optimum Design of Rotational Inertial Tuned Mass Dampers,ion absorbers. The fixed-points technique is based on the existence of fixed points on the system’s frequency response curve that are independent of the system’s damping level and are thus at the same location during both the zero and infinite damping conditions. Optimum tuning parameter of tuned ma

Covariance-Driven Stochastic Subspace Identification of an End-Supported Pontoon Bridge Under Varyi-driven Stochastic Subspace Identification (Cov-SSI), the modal parameters of the bridge are estimated. The results are interpreted in the context of the environment, represented by significant wave heights. The problem is characterized by the fact that modes are closely spaced in frequency and have

Effects of Seismic Retrofit on the Dynamic Properties of a 4-Storey Parking Garage, Columbia in Vancouver, Canada. A similar test was conducted in March 2014 before the Parkade was subjected to different interventions for seismic retrofit purpose between July and October 2014..Natural frequencies, modal damping and mode shapes were identified with the Frequency Domain Decompositio

Analytical and Experimental Study of Eddy Current Damper for Vibration Suppression in a Footbridge nd turbine braking systems as well as in car vibration control systems. Vibration control approaches for civil engineering structures still usually rely on more traditional approaches, such as viscous and tuned mass dampers. The use of novel Eddy current damping devices has the potential to compleme

Nonlinear Damping in Floor Vibrations Serviceability: Verification on a Laboratory Structure,. This is known as nonlinear damping or amplitude-dependent damping. While the nonlinear characteristics of damping have been studied thoroughly for earthquake and wind loading excitations; it has not been comprehensively studied for floor vibration serviceability applications..This paper focuses on
