Analysis Of Free Vibration And Wind-induced Vibration Control Of Tall Structure

The comprehension studies on the free vibration and wind induced vibration control of the tall structures and obtains the natural frequency and wind-induced vibration response of the tall control structures. the main contents as following :1. First of all, the Euler beam model is used to analyze the free vibration of the short-pier shear wall structures and the short-pier shear wall structures that consider the role of wall-beam. Secondly, the Rosman method establish the free vibration equation of the single-span short-pier shear wall, the multi-span short-pier shear wall, and the thin tube column frame structures and give examples.2. D'Alembert principle established motion equations of the short-pier shear wall structures which consider the role of wall-beam under the wind load effect. According to the random vibration theory, the article obtain the short-pier Shear Wall response analysis, that were based on existing norms Davenport Wind.3.The article establish motion equations of the Short-pier shear wall structures with TMD or TLD under wind load. The complex mode method is used to directly on disconnect the vibration equation of the short-pier shear wall structures. The structure were expressed in the first vibration mode control with TMD or TLD the analytical expression of wind vibration response. An example is given to show how to use this method.4. The stochastic averaging method is used to analyze the response of the structure considering the support with viscous fluid damper of random wind load, and obtain probability density function of displacement and speed and variance of displacement and speed. Example shows that structure with viscous fluid dampers wind resist wind is very clear.
