|
摘要
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。
According to the effects of parameters of energy dissipation damper on its damping performance,the link element in SAP 2000 was used to simulate the energy dissipation damper,Wen model unit was used for friction damper,and Maxwell model unit was used for viscous damper,the interface program of MATLAB and SAP 2000 on the MATLAB software platform was established.Using time history analysis,it was respectively calculated the variation rules of structural control effect indexes along parameters when friction damper structure and viscous damper structure were under earthquake action,their better results were given and their control effects were compared.The results show that the energy dissipation damper parameters have important influences on its damping performance,when the parameters are reasonable enough,both friction damper and viscous damper can effectively control the structural displacement and acceleration,but have different control effects.
