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。
The nonlinear seismic response analysis of two adjacent high-rise reinforced concrete structures connected with Maxwell model under large earthquake is carried out. The constitutive model of the adjacent structure adopts the three-line stiffness degradation model, and the adjacent adjoining Maxwell-type damper The equations of motion of Maxwell dampers are studied, and the applicability of Maxwell dampers optimization parameters in non-linear phase is researched. The influence of collision on the seismic response of adjacent structures is studied. The optimal parameter values of dampers under different seismic waves are proposed. . The analysis results show that when the adjacent structure enters the non-linear phase, the dampers with stronger damping energy dissipation needs to be connected to control the seismic response of the two structures. Even with the smaller width of the anti-vibration gap, Structure under the action of a large earthquake is also less likely to collide.
