【Abstract】 In this paper,the viscoelastic structure is treated as a control system, and the nonlinear force produced by the viscoelastic damper is simulated by Kelvin model and standard solid model.The differential equations of the motion of the viscoelastic structure are described by state space method with dynamic simulation carried out through the SIMULINK toolbox in MATLAB.At last an example about five floor reinforced concrete structure is given.更多还原
