摘要

    摘要
  • 摘要: 对连接Maxwell模型的两相邻高层钢筋混凝土结构进行了大震作用下的非线性地震反应分析,相邻结构的本构模型采用三线型刚度退化模型,推导了连接Maxwell型阻尼器的相邻结构的运动方程,研究了Maxwell阻尼器优化参数理论表达式在结构进入非线性阶段的适用性,并研究了碰撞对相邻结构地震响应的影响,提出了不同地震波激励下阻尼器的优化参数值。分析结果表明：相邻结构进入非线性阶段时需要连接具有更强阻尼耗能能力的阻尼器以控制两结构的地震响应;即便在较小的防震缝宽度下,连接了控制装置后的相邻结构在大震作用下发生碰撞的可能性亦较小。
    Abstract: Nonlinear seismic response analysis was performed on two adjacent high-rise reinforced concrete structures, which are connected using the Maxwell model, under large earthquakes. The constitutive model of the adjacent structures is modeled using the three-line stiffness degradation model. The motion equations of the adjacent connected structures are derived. The applicability of the theoretical expression of Maxwell damper optimum parameters and the effect of collisions on the seismic response of adjacent structures have been investigated. This paper proposes different optimization parameters for dampers under different excitations. The results show that, in order to control the seismic response of the adjacent structures, they need to be connected with dampers which have stronger damping energy dissipation when entering the nonlinear stage; even with a smaller seismic joint, the possibility of collision is still small for the adjacent structures under strong earthquakes when connected with control devices.
