Wind-Induced Vibrations and Gust Response Factors of the Cabin–Cable–Tower System
Symmetry, 2023 A large-scale radio astronomical telescope is a typical complex coupled system, consisting of a feed cabin, cables, and supporting structures. The system is extremely sensitive to wind loads, especially the feed cabin, which has high requirements for vibration displacement during operation, and excessive vibration may affect normal operation.

Mode-superposition response spectrum method for wind-induced vibration analysis of structures [PDF]
Vibroengineering Procedia, 2020 The calculation process of time history analysis method is complicated and time-consuming which is not convenient for wide application and promotion in engineering design. Based on the idea of mode decomposition in structural seismic response analysis, the fluctuating wind response spectrum and the mode decomposition response spectrum method for wind ...

Downburst-Induced Vibration Coefficient of Long-Span Roof Structures
Buildings, 2022 Long-span roof structures are vulnerable to being damaged by downbursts due to the sensitivity of such structures to wind loads. However, there is still no simple and practical method for the downburst-resistant design of such structures to date ...

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 ...
