【摘要】 本文讨论了利用黏性阻尼和复阻尼模型求解结构动力响应的方法;按相同的阻尼比,分别采用复阻尼模型和黏性阻尼模型计算了两个框架结构在不同地震波作用下的响应,并将结果进行对比,分析了两种不同的阻尼模型对结构动力响应的影响。结果表明,采用不同类型的阻尼对结构响应影响很大。更多还原

【Abstract】 The methods for solving structural dynamic responses by using viscous damping and complex damping models are discussed. With equal damping ratio,complex damping model and viscous damping model are used to calculate the responses of two frame structures under various seismic ground motions separately,and the contrast of the results is made and the influence of structural dynamic responses between two different damping models is analysed.It is shown that the damping has great influence on the structural dynamic responses.更多还原
