摘要
对带支撑粘弹性阻尼器单自由度耗能结构的随机地震响应进行了研究。首先建立了结构运动方程,然后应用频域法获得结构位移响应方差的解析解,并给出算例,分析表明了阻尼器的减震效果及支撑对减震效果的影响。
The random seismic response of a SDOF consumption structure with supporting for viscous elastic damper were studied.Firstly,the structure equation of motion is established.Then the structural displacement response variance analytic solutions is gained with applying the frequency domain method solves the.And a numerical example is presented.The conspicuous damping effect and support shock effect of the damper is analyzed.
