Abstract: A direct eigenvalue analysis approach to solving the stability problem of randomly and periodically parametrically excited linear systems is developed based on the response moment stability, Floquet theorem, Fourier series, ...

Abstract: A train-bridge system (TBS) is inevitably subjected to parameter uncertainty, which leads to variability in its dynamic responses. In practice, it is difficult to characterize parameter uncertainty using precise probability ...

Abstract: Structural health monitoring (SHM) is the process of conducting structural condition diagnosis and prognosis based on appropriate analyses of in situ measurement data. Direct assessment of structural condition using time ...

Abstract: Identifying critical unknown parameters in structures is important for evaluation of structural performance and structural health monitoring. However, like most inverse problems, certain difficulties exist in the identification ...

Abstract: A train–rail–bridge (TRB) interaction model of vector mechanics (VM) is developed to predict the derailment of a train traveling over cable-supported bridges under crosswinds. The aerodynamic coefficients measured from the ...

Abstract: There exist so many approaches to extract the time-varying mean (TVM) of nonstationary wind speeds under the nonstationary wind speed model, such as the wavelet transform and empirical model decomposition. These approaches ...
