## 6 Conclusions  
We proposed a wind-induced vibration control strategy based on the two-domain coupling and cooperative optimization of wind spectrum and response surface, focused on solving the optimization problem of the dynamic reliability of tall boom structures under the action of unsteady wind fields, and drew the following conclusions:  
1. We establish a dual-domain coupled analysis framework for turbulent pulsation and structural optimization, which integrates fluid-structure coupling and response surface optimization design, breaking through the limitations of traditional single-domain analysis (e.g., only wind study of the structure or independent optimization design). The results show that the maximum displacement is reduced by 8.06%, the maximum stress is reduced by 11.04%, and the structural stiffness is improved. Meanwhile, the actual stress monitoring proves the feasibility of this method, which provides a new research idea for the wind response and structural optimization of scalable towering structures. 2. Under the action of random wind loads, the traditional optimization method of the structure requires hundreds of iterations (each iteration requires a complete CFD analysis). The dual-domain coupled optimization only needs selection of the external dimensions according to the most unfavorable location of the structure. A few sample points can construct the response surface of structural dimensions. The response surface dimensions can be screened to find the best-fitting dimensions of the structure to cope with the wind response, which simplifies the process of structural wind response and optimization and improves the efficiency of the study. 3. Since this paper only investigates the horizontal extension mechanism toward the ground, potential problems such as chaotic structural response and damage misreporting need further investigation. Considering the limitations of this paper, the wind spectrum-response surface two-domain coupling can be generalized to similar towering structures, and in the future, we will further explore the mechanism of forming a certain angle with the ground and make an in-depth exploration, such as

This ensures applicability to a broader range of structures and guides cross-scale wind studies of high-altitude retractable devices. * 4 In the future, multimodal sensors and threshold alarm systems can be integrated into the machines. The main study is in the critical area of the fourth and fifth sections of the jib joints, which can more accurately improve the monitoring accuracy, real-time response, and prevention. Still, we should pay attention to the economy of the large-scale deployment of sensors and the long-term maintenance costs. At the same time, delay in the data processing may lead to problems such as lagging response. Uncertainty factors, such as noise, can be introduced by adding other uncertainty factors, such as the turbulent noise term of the wind field, through stochastic equations when building a pulsating wind field, which can significantly improve the practical value of wind response analysis.
