Special Issue Information

Dear Colleagues,

Flexible structures—for example, long-span bridges, high-rise buildings, large-expanse roofs, and so on—are susceptible to the action of strong winds. The effects of wind on these structures have been important topics for the wind engineering community for the last century. Moreover, wind disasters have become more and more violent in the most recent few decades. Typical, frequently encountered wind disasters involve hurricanes/typhoons, tornados, downbursts, and so on. All of these extreme events have a great impact on structures and pose a considerable threat to structural safety. To enhance our understanding of wind effects on these structures and provide a more reliably wind-resistant design, more research efforts are required on the monitoring, analysis, and control of flexible bridges under strong winds.

The proposed Special Issue aims to collect recent advances in the field of wind effects on structures by gathering scientific breakthroughs on the monitoring, analysis, and control of flexible structures under strong winds. The papers to be included in the Special Issue will cover a broad range of theoretical and applied topics of interest. Papers including, but not limited to, the given topics below are encouraged to submit to this Special Issue.

  • Characteristics of strong winds;
  • Characterization of extreme wind events;
  • Simulation of random wind field;
  • Structural aerodynamics under strong winds;
  • Monitoring scheme optimization of structural wind effects;
  • Performance evaluation of flexible structures under strong winds;
  • Non-stationary/Non-Gaussian analysis of wind-induced responses;
  • Wind-induced vibration control of flexible structures.

Much work has been devoted to the investigation and understanding of the flow-induced vibrations of twin cylinders vibrating individually (e.g., vortex-induced vibration and wake-induced galloping), but little has been devoted to coupled twin cylinders with synchronous galloping. The primary objective of this work is to investigate the aerodynamic forcing characteristics of coupled twin cylinders in cross flow and explore their effects on synchronous galloping. Pressure measurements were performed on a stationary section model of twin cylinders with various cylinder center-to-center distances from 2.5 to 11 diameters. Pressure distributions, reduced frequencies and total aerodynamic forces of the cylinders are analyzed. The results show that the flow around twin cylinders shows two typical patterns with different spacing, and the critical spacing for the two patterns at wind incidence angles of 0° and 9° is in the range of 3.8D~4.3D and 3.5D~3.8D, respectively. For cylinder spacings below the critical value, vortex shedding of the upstream cylinder is suppressed by the downstream cylinder. In particular, at wind incidence angles of 9°, the wake flow of the upstream cylinder flows rapidly near the top edge and impacts on the inlet edge of the downstream cylinder, which causes a negative and positive pressure region, respectively. As a result, the total lift force of twin cylinders comes to a peak while the total drag force jumps to a higher value. Moreover, there is a sharp drop of total lift coefficient for α = 9–12°, indicating the potential galloping instability. Finally, numerical simulations were performed for the visualization of the two flow patterns. Full article
