Special Issue Information

Dear Colleagues,

This Special Issue aims to focus on the latest research and applications of the Structural, Architectural, Urban Planning and Meteorological Aspects of Wind Actions. Issues related to the development of knowledge regarding wind engineering are of great significance in terms of wind modeling and the response of structures to wind. These elements contribute to the correct design of objects and structures, and the selection of the optimal shape of houses and infrastructure with regard to the effects of wind. Correct wind modeling influences the proper urban shaping of cities and houses, ensuring wind comfort and, most imprtantly, adequate ventilation, especially in city centers with high levels of pollution. Architects and urban planners can design buildings and their locations to create special natural ventilation zones. The dynamics of climate change and increasing urban development require the revision of regulations and recommendations in the architectural, urban and structural design of facilities and houses. Climate change is starting to cause extreme winds such as tornadoes that have not occurred in certain locations previously. These factors require new insights into wind engineering research and the development of theoretical and numerical models and tests in wind tunnels and in situ. This requires a collaboration between architects, urban planners, structural engineers and meteorologists.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  1. Architectural shaping of objects due to the optimal response of the building to wind;
  2. Urban shaping of space due to wind comfort and natural ventilation zones;
  3. Extreme winds and their impacts on structures and infrastructures;
  4. Modeling of extreme wind and tornadoes;
  5. Case studies of extreme winds and outbreaks;
  6. Computational fluid dynamics in the scope of air movement;
  7. Numerical wind simulations;
  8. Wind tunnel simulations;
  9. Wind scales, their update and development;
  10. Wind comfort;
  11. Damages caused by winds;
  12. Wind-resistant design of structures;
  13. Engineering solutions resistant to winds;
  14. Energy from wind;
  15. Future of wind turbines technology;
  16. Development of onshore and offshore wind turbines;
  17. Meteorological aspects of winds.

With the widespread adoption of 5G telecommunication networks, to reduce construction costs, it has become necessary to add new equipment or antennas to existing 4G and 3G telecommunication towers. This significantly changes the original aerodynamic shape of the towers, leading to a substantial increase in the wind load, which may exceed the original structure’s bearing capacity and pose a threat to the structure’s safety. This study employed three-dimensional numerical simulation methods to systematically investigate the impact of various antenna arrangement parameters, such as the arrangement number, arrangement form, and arrangement layers, on the wind load characteristics of telecommunication towers. The findings revealed that the antenna arrangement form significantly affects the sensitivity of the telecommunication tower’s wind load to the wind direction, with more uniform antenna arrangements resulting in less sensitivity. Compared to the drag coefficient and the windward base overturning moment coefficient, the tower’s lateral force coefficient and the crosswind base overturning moment coefficient are more sensitive to changes in the wind direction. The change patterns in the tower’s overturning force coefficient and overturning moment coefficient with the antenna arrangement number are essentially the same. However, as the antenna arrangement number increases, the growth rate of the tower’s overturning moment coefficient is about twice that of the overturning force coefficient. The tower’s overturning force coefficient increases approximately linearly with the increase in antenna arrangement layers, while the tower’s overturning moment coefficient exhibits a nonlinear increase with the increase in antenna arrangement layers. The rate of increase in the wind load with the antenna arrangement layers is significantly greater than that with the antenna arrangement number. Thus, to reduce wind load, it is advisable in practical engineering applications to increase the antenna arrangement number per layer, thereby reducing the antenna arrangement layers. The study also summarized a calculation method for the structural wind load of telecommunication towers, taking into account the influence of antenna arrangement parameters, providing a reliable basis for the structural design and safety assessment of telecommunication towers in practical engineering.
