When vehicles interact with a bridge, vehicle–bridge interaction (VBI) system is created. The frequency and modal shape of VBI systems have been widely studied, but the damping has not adequately investigated. In recent years, several incidents abnormal bridge vibration due to changes in occurred aroused widespread concern society. Damping an important evaluation index structural dynamic perfor...

This paper presents a new moving force identification (MFI) algorithm that uses measured accelerations to infer applied vehicle forces on bridges. Previous MFI algorithms use strain or deflection measurements. Statistics of the inferred are used in turn as indicators global bridge damage. The acceleration-based (A-MFI) is validated through numerical simulations with coupled vehicle-bridge dynam...

In this paper, we use a scale model to experimentally validate an indirect approach to bridge structural health monitoring (SHM). In contrast to a traditional direct monitoring approach with sensors placed on a bridge, the indirect approach uses instrumented vehicles to collect data about the bridge. Indirect monitoring could offer a mobile, sustainable, and economical complementary solution to...

This paper proposes a new methodology to simulate wind fields that are non-orthogonal the structure and traffic direction, it presents first wind–vehicle–bridge interaction (W-VBI) analysis framework account for skew effects on driving safety. The three-directional generated match well target frequency content correlation properties along deck. W-VBI is applied study of vehicles crossing long b...

Vibration analysis of bridges induced by train loads is a crucial aspect railway design, particularly considering the complexity vehicle components such as bogie-suspension systems. Consequently, engineers have endeavored to improve computational efficiency and applicability models using finite-element method. This paper introduces toolbox implemented in ABAQUS through user-defined element (UEL...
