Numerical simulation of the airflow–rivulet interaction associated with the rain-wind induced vibration phenomenon [PDF]
, 2011 Rain-wind induced vibration is an aeroelastic phenomenon that occurs on the inclined cables of cable-stayed bridges. The vibrations are believed to be caused by a complicated nonlinear interaction between rivulets of rain water that run down the cables ...

The Wind-Induced Vibration Response for Tower Crane Based on Virtual Excitation Method [PDF]
The Open Mechanical Engineering Journal, 2014 The dynamics of Tower Crane is complicated by wind excitation which complicates the wind-induced vibration response analysis. The random wind-induced response analysis of tower crane is presented based on finite element method and virtual excitation method. The pulsating wind loads change into multiple-point correlation stationary excitation.

Nonstationarity analysis in wind-rain-induced vibration of stay cables
Journal of Civil Engineering and Management, 2012 Wind and wind-rain-induced cable vibration are usually nonstationary. Based on the field measured wind data from the Dongting Lake Bridge (DLB) in China, a wavelet-based method was developed to investigate the wind characteristics of wind-rain-induced ...

Numerical Analysis on Spanwise Correlation of Vortex-Induced Force of Split Double-Box Beam
Applied Sciences, 2022 The vortex-induced force of bridges is not synchronized along the span direction. The spatial correlation of vortex-induced force becomes obvious when the span of the bridge structure gradually increases, and the mass gradually decreases.

System Identification of Constructed Facilities: Challenges and Opportunities Across Hazards [PDF]
, 2008 The motivation, success and prevalence of full-scale monitoring of constructed buildings vary considerably across the hazard of concern (earthquakes, strong winds, etc.), due in part to various fiscal and life safety motivators.
