Dynamic characteristics and wind-induced vibration coefficients of purlin-sheet roofs
Steel and Composite Structures, 2016This paper presents the dynamic characteristics analysis of the purlin-sheet roofs by the random vibration theories. Results show that the natural vibration frequency of the purlin-sheet roof is low, while the frequencies and mode distributions are very intensive.

The Analysis of Wind Vibration Coefficient of Long-Span Dome Structures with Different Thickness
Earth and Space 2012, 2012In this study, wind vibration coefficient and the most unfavorable part of wind-induced vibration of a long-span thin shell dome structure are investigated, by using the finite element method to analysis three dimensional wind vibration in time domain.

Investigations on the Wind Vibration Coefficient of Single Layer Lattice Barrel Vault Structures
Advanced Materials Research, 2014Wind actions on the structures consist of two parts, the average action and the fluctuation action. The fluctuation action will cause the structures vibrating and enlarge the wind action of the structures. This paper investigates the wind vibration coefficient for the single layer lattice barrel vault structures.

Analysis of Rain-Wind Induced Cable Vibration Using Spatially Measured Aerodynamic Coefficients
Advances in Structural Engineering, 2014In most currently-used analytical models for studying rain-wind induced cable vibration, wind velocity relative to cable motion was determined by trigonometric decomposition and the aerodynamic coefficients of a cable were measured through wind tunnel tests using a horizontal cable model with two-dimensional flow field.

Abstract The study focuses on vibration response based health monitoring for an operating wind turbine, which features time-dependent dynamics under environmental and operational uncertainty. A Gaussian Mixture Model Random Coefficient (GMM–RC) model based Structural Health Monitoring framework postulated in a companion paper is adopted and assessed.

Existing studies on the wind-induced vibration response of large-span flexible photovoltaic supports mostly focus on local measurement points and ignore the spatial variability of structural aeroelastic responses. Most researches also concentrate on the wind vibration coefficient of vertical displacement, without considering the effect of three ...
