本文提出了一种耗能减震加层结构新体系，即利用旧有建筑顶层与加层结构之间的摩擦垫层井依靠在两结构各层连接点处增设的耗能阻尼器来吸收耗散能量的减振体系。在进行非线性动力分析过程中，首次建立了系统的结构模型，引入了一种新的库仑摩擦力表达式并对影响体系减振率的有关参数进行了研究。最后通过对一实际工程的设计和计算，验证了这种加层减振做法的有效性。 In this paper, a new system of energy dissipation and shock absorption plus layer structure is proposed, which uses the friction cushion between the top layer of the old building and the additional layer structure and absorbs the energy loss by relying on the energy dissipation damper added at the connection points of the two layers Vibration damping system of scattered energy. In the process of nonlinear dynamic analysis, the structural model of the system was established for the first time. A new Coulomb friction expression was introduced and the parameters affecting the damping rate of the system were studied. Finally, through the design and calculation of an actual project, the effectiveness of this method is verified.
