摘　　要： 目前,建筑结构的稳定性受到人们广泛关注,非线性阻尼器是一种有效的减轻振动装置。为此,通过利用非线性阻尼器,调节和控制阻尼比,对河南砖瓦式建筑结构进行结构减振与振动控制。首先,引入非线性阻尼器,设计非线性阻尼器的力学模型,分析阻尼系统的动力性质,确定等效阻尼系数;其次,初步设计系统并完成等效单自由度体系曲线的建立,然后在减振结构中计算出等效周期及等效阻尼比,通过上述步骤获取的参数和初步设计系统的综合运用可以实现砖瓦式建筑结构减振与振动控制设计。仿真实验证明,建筑结构减振可以通过应用非线性阻尼器件的方法来实现。 At present,the stability of building structures is widely concerned.Nonlinear damper is an effective vibration reduction device.Therefore,the structural vibration reduction and vibration control of Henan brick and tile structure are controlled by using nonlinear dampers to adjust and control the damping ratio.First of all,the introduction of nonlinear damper,mechanical model of nonlinear damper design,analysis of dynamic properties of damping system,the determination of equivalent damping coefficient;secondly,the establishment of the system and complete the preliminary design of the equivalent single degree of freedom system curve,then calculate the equivalent damping structure cycle and equivalent damping ratio,the integrated use of parameters are obtained through the above steps the preliminary design and the system can realize the tile type building structure vibration control and vibration control design.Simulation results show that the vibration reduction of building structures can be achieved by applying nonlinear damping devices.
