Web26 de fev. de 2024 · 3.3 Modelling of the Bridge–Vehicle System with TMDI (When an Inerter Device is Connected Between TMD Mass and a Fixed Support/pier) The second terminal of the inerter device is here considered fixed so that the maximum inertance effect can be achieved. The force generated by the inerter is given by \(F=b\left(\ddot{d} … WebThis study proposes a novel reduced-order model (ROM), based on the Volterra series, for the aerodynamic force of the bridge deck section. Moreover, the ROM of the aerodynamic force of the streamlined box girder section of the Great Belt East Bridge (GBEB) is identified with computational fluid dynamic (CFD) simulations. Furthermore, an analysis …

Firstly, the vibration of a massive cable which is connected to a vibrating cable-stayed bridge deck and pylon is presented analytically. Equations describing a change of the cable's force and its eigenvalues due to the cable’s undamped and damped vibrations are also derived. Mathematical lamped models
