TMD 超高层建筑的风致横风向响应分析和控制的开 题报告 Introduction The construction of high-rise buildings has become increasingly prevalent with the growth of urbanization. However, these tall buildings are often subjected to wind-induced vibrations, which can cause discomfort to occupants and potentially lead to structural damage. Therefore, it is important to analyze the wind-induced response of high-rise buildings and consider methods of controlling their vibrations, such as using tuned mass dampers (TMDs). Research Objectives The objective of this research is to analyze the wind-induced response of high-rise buildings in terms of cross-wind vibrations and propose the use of TMDs as acontrol mechanism. Research Methodology Firstly, aliterature review will be conducted to examine previous research on the wind-induced response of high-rise buildings and the effectiveness of TMDs. The methodology will then proceed to conduct a finite element analysis of aselected high-rise building to simulate the cross-wind vibrations experienced by the structure. The response of the structure will be analyzed, including its natural frequencies, modes of vibration, and damping ratios. The inclusion of TMDs and their effectiveness in controlling the vibrations will also be investigated. Expected Outcomes It is expected that this research will provide abetter understanding of the wind-induced response of high-rise buildings in cross-wind directions and the effectiveness of TMDs in controlling vibrations. The results of this study can be used to improve the design and construction of high-rise structures and increase occupant comfort and safety. Conclusion In conclusion, the wind-induced response of high-rise buildings in cross-wind directions is an important consideration for their design and construction. The use of TMDs has been proven effective in controlling the vibrations of these tall structures. This research project aims to
