Traffic Hazards on Main Road’s Bridges: Real-Time Estimating and Managing the Overload Risk

IEEE Transactions on Intelligent Transportation Systems, Год журнала: 2024, Номер 25(9), С. 12239 - 12255

The risk associated with extreme traffic loads on bridges has seldom been explored, State-of-the-art evaluation methods being time-consuming and unsuitable for fast management. Traditional management advocates optimizing offline bridge maintenance plans. In contrast, novel approaches that can assess manage this live through Intelligent Transportation Systems (ITSs) are lacking. This study addresses these gaps a three-block framework. It utilizes Weigh-In-Motion (WIM) systems collecting bridge-specific load data, develops probabilistic Risk Prediction Model estimating the frequency severity of overloading events drawing current Structural Design Codes (SDCs), simulates an ITS-based architecture implementing actions. framework was tested 2.5M $+$ WIM raw data records gathered from ring road Brescia, Italy. Results showed design were overcome more frequently than SDCs prescriptions, violations Traffic Code mass limit significantly affected predictions. These findings underscore need increased attention when issuing permits extremely overweighted vehicles encourage enforcement strategies implemented by architectures real-time

Investigation of sensitivity analysis of crucial dynamic characteristics of offshore wind turbine utilizing polynomial chaos expansion

Journal of Offshore Mechanics and Arctic Engineering, Год журнала: 2025, Номер 147(5)

Опубликована: Янв. 31, 2025

Abstract The probabilistic-based design method is gaining attention in designing offshore wind turbines (OWTs) owing to its economic design. However, the numerous uncertain variables and tiny target annual failure probability make it unaffordable achieve a reliable Conducting sensitivity analysis (SA) common strategy identify nonsignificant variables, thereby reducing uncertainty space accelerating process. To this end, study aims factors significantly influencing dynamic characteristics of OWTs from structural geometrical, material properties, environmental, soil uncertainties by conducting SA. Primarily, an improved integrating polynomial chaos expansion (PCE) with traditional Morris screening was proposed accelerate SA process, further validated comparing natural frequency results those PCE-based Sobol method. A comprehensive then carried out explore dominant highly representative responses using indicated that pile foundation bending stiffness has remarkable effect on following Young's modulus E tower thickness t, loads serve as most prominent factor support responses. Furthermore, according observed influence parameter stress, proved necessity introducing coupled numerical model for OWT.
