摘　　要：在结构连续化假定的基础上,提出了基底隔震结构的剪—弯梁隔震模型,导出了问题的控制微分方程,求出了相应矩阵形式的初参数解,给出了该模型下的频率方程及振型函数的解析表达式。By assuming the building to be continuous, the shear-bending beam model of the base-isolated structures was proposed. The manipulative differential equation of the model was derived and the initial parameter solutions with the matrix forms were obtained. The frequency equation and the vibration modes function were given in the analytic forms.
