Wind Testing

"Wind engineering is an essential field to understand the impacts of wind on humans, man-made structures, wind turbines, vehicles, and the environment at large. In wind engineering, researchers investigate the effects of wind on natural and built environments and study the possible damage, inconvenience, or benefits that may result from wind or airflow. Wind engineering draws on meteorology, fluid dynamics, mechanics, geographic information systems, aerodynamics, and structural dynamics. Atmospheric boundary-layer (ABL) simulations at a relatively high resolution (spectral content and turbulence) are essential for accurate estimation of loading on structures and machines and the extracted power from wind. The physics involved in the processes of ABL and the flow interaction are indispensable for understanding wind-induced loads. Several tools are available for wind engineering investigations: atmospheric models, wind tunnels, open-jet testing, and computational fluid dynamics (CFD). We solicit high-quality original research or review papers focused on state-of-the-art techniques and methods employed in flow, aerodynamic, and aeroelastic measurements in wind engineering of civil infrastructure, vehicles, planes, and wind turbines. Potential topics include, but are not limited to: aeronautical wind tunnels, boundary layer wind tunnels, open-jet facilities, computational and theoretical methods for wind load assessment; aerodynamic forces on vehicles; wind forces and pressures on low-rise buildings, high-rise buildings, bridges, power transmission towers, solar energy harvesters, wind turbines; non-synoptic wind processes, tornadoes, and down-burst; aeroelasticity and fluid-structure interaction; Reynolds number effects; atmospheric turbulence; and aerodynamic optimization for improved sustainability with resilience benefits."

Abstract: Wind, wave, and seismic hazards, coupled with aging and vulnerable structures, pose the potential for damage and loss of life and property. Multihazard forces can wreak catastrophic damage to buildings, bridges, wind turbines, offshore structures, and the infrastructure in general. Consequently, vibration control of structures is indispensable for their safety and serviceability under multihazard loads. Several control techniques can be employed.

Call for Papers: Risk, Reliability, and Uncertainty Quantification of Structural Systems Subjected to Shock and Vibration

Deterministic analysis methods, even based on detailed modeling, may not precisely reflect the reliability of engineering structures. The alternative is to perform risk analysis under the probabilistic assumption and propagate the uncertainty in different design variables. This is a crucial task, especially for structures subjected to shock and vibration. The design and analysis of ordinary structures subjected to single and multiple hazard dynamic loads are real-world related engineering applications: critical dams and nuclear power plants under hydrodynamic shock and earthquake impact; synoptic and non-synoptic wind-induced structural vibrations; vehicle-induced vibrations in bridges; wind, wave, and seismic impact on offshore structures and wind turbines; earthquake-induced vibrations in structures; and so on. In this special journal issue, we solicit high-quality articles of original research focused on the state-of-the-art techniques and methods employed in risk, reliability, and uncertainty quantification in infrastructure systems, with or without control/mitigation devices, subjected to shock and vibration. We welcome theoretical and application papers of high technical standards across various disciplines, thus facilitating awareness of techniques and methods in one area that may apply to other areas. We seek high-quality submissions of original research and review articles on all aspects related to risk, reliability, and uncertainty in shock and vibration applications. For example, fundamental research and practical applications in civil, mechanical, and aerospace engineering.

The topics include, but are not limited to, the following:

• Safety, reliability, risk, and life-cycle performance of structures and infrastructures subjected to shock and vibration
• Uncertainties associated with extreme return periods of wind and earthquake loadings acting on structures
• Reliability considerations for wind turbines under multiple hazard dynamic loads
• Risk, reliability, and uncertainty quantification in the evaluation of the response of structures to windstorms and earthquakes
• Risk, reliability, and uncertainty quantification in passive, active, and semiactive structural control
• Uncertainties in complex dynamic modeling and control of structures under multihazards
• Reliability in structural monitoring under shock and vibrations
• Modelling and analysis of metamaterials for vibration mitigation
• Effects of passive, active, and semiactive structural control on reliability and sustainability of aging structures
• Risk, reliability, and uncertainty in real-time hybrid simulation

The submission Deadline is Friday, 27 April 2018. Publication Date September 2018. Papers are published upon acceptance, regardless of the Special Issue publication date.

Call for Papers: Vibration Control in Structures for Multihazard Loadings — Shock and Vibration

Wind, wave, and seismic hazards, coupled with aging and vulnerable structures, pose the potential for damage and loss of life and property. Multihazard forces can wreak catastrophic damage to buildings, bridges, offshore structures, and the infrastructure in general. Although an individual hazard may be more significant than the other, the rapid population growth and economic development have greatly increased the potential of exposure to multiple hazards. Current design codes and hazard mitigation strategies treat hurricanes and earthquakes as completely independent, which does not account for the increased risk to structures in regions where both hazards are present. Consequently, vibration control of structures is indispensable for the safety and serviceability of the infrastructure under multihazard loadings. To do so, several control techniques can be employed. In this Special Issue, we solicit high quality original research articles as well as review articles focused on the state-of-the-art techniques and methods employed in the control of structures under multiple hazards. Potential topics include but are not limited to the following:

• Vibration control in buildings for wind and earthquakes
• Vibration control in bridges for wind and seismic hazards
• Vibration control in offshore structures for wind and waves
• Vibration mitigation in flexible structures for improved resilience and performance under synoptic and nonsynoptic wind loadings
• Aerodynamic optimization under synoptic and nonsynoptic wind loadings for improved sustainability with resilience benefits
