Abstract

Vortex-induced vibration (VIV) significantly affects ride comfort and may necessitate traffic restrictions, disrupting economic and social activities. The combined impact of VIV and traffic on ride comfort is not well understood, and existing studies are often too time-consuming for timely bridge management decisions. This study aims to explore ride comfort on long-span suspension bridges (LSSBs) during VIV and develop an online prediction model for real-time evaluations, aiding bridge management decisions. A vortex-traffic-bridge (VTB) simulation platform is established to extract vehicle dynamic responses and calculate motion sickness incidence (MSI) for evaluating ride comfort during VIV. MSI is treated probabilistically due to traffic flow's stochastic nature. The optimal probabilistic distribution model (PDM) for MSI data is identified using Jensen-Shannon divergence. A Gaussian process regression (GPR) surrogate model is constructed with VIV mode, VIV amplitude, and traffic density as inputs, and PDM parameters for MSI as outputs. A case study of a prototype LSSB using the GPR surrogate model thoroughly investigates the influence of VIV mode, VIV amplitude, and traffic density on MSI. This model can timely predict drivers' MSI under VIV, aiding effective bridge management decisions.

期刊介绍： The objective of the journal is to provide a means for the publication and interchange of information, on an international basis, on all those aspects of wind engineering that are included in the activities of the International Association for Wind Engineering http://www.iawe.org/. These are: social and economic impact of wind effects; wind characteristics and structure, local wind environments, wind loads and structural response, diffusion, pollutant dispersion and matter transport, wind effects on building heat loss and ventilation, wind effects on transport systems, aerodynamic aspects of wind energy generation, and codification of wind effects. Papers on these subjects describing full-scale measurements, wind-tunnel simulation studies, computational or theoretical methods are published, as well as papers dealing with the development of techniques and apparatus for wind engineering experiments.
