## 1 Introduction  
Sender tower structures are widely used, such as in street lights, telecommunication towers, masts, etc. These structures are characterized by small cross-sections, large aspect ratios, and high flexibility, making them wind-sensitive structures. Wind load is one of the primary controlling loads in the design of slender tower structures and has a critical impact on their safety. Wind tunnel testing is a reliable method to obtain the aerodynamic characteristics of slender tower-like structures. [PERSON] et al. [1], using wind tunnel tests, found that polygonal towers have better aerodynamic stability and vibrational response than traditional circular towers. [PERSON] et al. [2] focused their wind tunnel experimental studies on the aerodynamic loads during the pre-assembly stage of offshore wind turbine towers, discovering that the height of the tower significantly impacts aerodynamic loads. [PERSON] et al. [3] used aeroelastic models to assess the response of multi-span transmission line systems under various wind speeds and directions, indicating the differences in aerodynamic response between multi-span systems and individual lattice towers. [PERSON] et al. [4] studied the aerodynamic coefficients of single cylindrical bodies and developed a local calculation method to compute the wind loads on lattice structures. [PERSON] et al. [5] measured the drag coefficient and interference factors of square-section lattice towers with dish antennas through wind tunnel experiments, finding that interference factors depend on wind direction and the position of antennas on the tower section. [PERSON] et al. [6] explored the uncertainty in the response of tower structures to storm oscillations, emphasizing the importance of the accurate estimation of wind speed extremes, structural damping, and aerodynamic coefficients in assessing tower responses. [PERSON] et al. [7] conducted wind tunnel tests to measure the wind loads on a model of the Foshan TV tower, comparing the experimental results with those calculated using the complete quadratic combination method. In recent years, many scholars both domestically and internationally have begun to research the wind resistance of slender tower structures using numerical simulation methods. [PERSON] et al. [8] used a 3D computational model to assess the aerodynamic behavior and structural stability of the Brasilia Telecommunications Tower, finding that antennas and brackets significantly affect aerodynamic forces and response amplitudes. [PERSON] et al. [9] proposed a high-fidelity simulation method, which was validated against field measurement data, demonstrating its potential in assessing transient effects induced by wind on slender structures. [PERSON] et al. [10] introduced a new method for controlling the along-wind vibration of chimneys by adjusting the lining, which was proven to be more effective than traditional dampers through validation with beam models and finite element shell models. [PERSON] et al. [11] combined numerical simulation and wind tunnel testing to study the effects of wind on lattice structures, exploring the vortex resonance excitation mechanisms of these structures. [PERSON] et al. [12] proposed a method for the wind-resistant dimensional optimization of lattice structures, emphasizing the importance of geometric nonlinear analysis and constraints of nonlinear critical load factors. [PERSON] et al. [13] analyzed wind-induced fatigue in guyed lattice steel towers, pointing out that the modular connection area is the most critical part for fatigue damage. [PERSON] et al. [14] conducted studies on the aerodynamic performance of single-pole telecommunication towers using both wind tunnel tests and numerical simulations, demonstrating that numerical simulation techniques can serve as an effective alternative to wind tunnel tests for assessing the aerodynamic behavior of single-pole telecommunication towers.
