针对耗能阻尼器参数对其减震性能的影响,采用SAP 2000中的连接单元来模拟耗能阻尼器,摩擦阻尼器采用Wen模型单元,黏滞阻尼器采用Maxwell模型单元,在MATLAB软件平台上编制了MATLAB与SAP 2000的接口程序,采用时程分析,分别计算了摩擦阻尼器结构和黏滞阻尼器结构在地震作用下结构控制效果指标沿参数的变化规律,给出了二者的较优结果并比较了二者的控制效果。结果表明:耗能阻尼器参数对其减震性能有重要影响,当参数取得足够合理时,摩擦阻尼器和黏滞阻尼器对结构的位移和加速度都能起到有效控制,但控制效果有差异。
In view of the influence of the energy-dissipating damper parameters on its shock absorption performance, a connecting unit in SAP 2000 was used to simulate the energy-dissipating damper, the friction damper was Wen model unit, the viscous damper was Maxwell model unit, and MATLAB software platform The program of interface between MATLAB and SAP 2000 was compiled. The variation regularity of parameters along the parameters of structure control under the action of earthquake was calculated respectively by using the time history analysis. Results and compare the two control effects. The results show that the parameters of the energy dissipater have an important influence on the shock absorption performance. When the parameters are sufficiently reasonable, the friction damper and the viscous damper can effectively control the displacement and acceleration of the structure, but the control effects are different .
