Experimental and numerical investigations on wind characteristics and wind induced vibrations of bridge structures
… researchers and engineers. For such structures, wind load has become one of the most important dominant loads under consideration in the analysis and design of structures. Thus, accurate and reliable evaluations of the wind characteristics are critical, as the evaluations may provide a solid …

An Investigation of Anchor Nut Loosening and Review of Tightening Procedures for Anchor Rods in Highway Ancillary Structures
… unknown. Ancillary structures are susceptible to vibrations due to different wind loadings like natural gusts, vortex shedding, galloping, and truck-induced gusts. Wind-induced vibrations are believed to be one of the potential causes of anchor nut loosening. Previous research also suggests that …

Experimental and CFD Study of Wind-Induced Response for Bridge Cables with Ice accretion
… for several phenomena which might affect them. Wind and wind/rain induced vibrations for bridge stay-cables were comprehensively studied by researchers worldwide; however recent projects have identified a new type of cable vibrations caused by ice accretion formed around the cable circumference. …

Intelligent Monitoring of Powerline Vibrations - Sparse Sensing and Predictive Modeling Approach
Wind-induced vibrations (WIV), particularly Aeolian vibrations, pose a persistent threat to the structural integrity and operational lifespan of overhead power transmission lines. Traditional mitigation strategies, such as passive dampers, often lack adaptability to changing environmental …

Wind Dynamics of the Next Generation of Tall Timber Buildings
… such that they do not vibrate excessively under wind loading. Wind-induced vibrations must be minimised to ensure that the building's occupants remain comfortable and do not regularly experience motion sickness during high winds. Despite the difficulties with wind dynamics for the current …

Characterization, modeling and mitigation of vortex-induced vibration of slender cylinders
… observed to vibrate at large amplitudes under wind excitation. Vortex-shedding was found to be one of the primary excitation mechanisms which manifests itself as distinct characteristics of the resultant problematic vibrations. The objectives of the proposed research are to formulate a …

Design and Integration of Machine Learning-Based Vision System for Automated Power Line Inspection Using a Mobile Damping Robot
… stressors such as moisture, dust, and wind-induced vibrations contribute to surface degradation, including corrosion and fretting, which compromise conductor conditions and therefore performance over time. This thesis presents a vision-based, autonomous inspection framework using a …

Investigation of a Mobile Damping Robot for Electric Transmission Lines
… lines suffer from many hazards, including wind-induced vibrations (WIV), which can lead to fatigue failure of the transmission conductors. Current vibration mitigation methods do not adequately address WIV because they overwhelmingly rely on narrow-band fixed absorbers. A mobile damping …

Performance based wind design and optimization of tall buildings considering the nonlinearity in building response
… tall buildings and other structures excited by wind loads has received much attention over the past few decades. The main objective of Performance Based Wind Design (PBWD) is to assess the adequacy of a structure in terms of the decision variables set forth by the stake holders. The performance …
