Response analysis on linear imbalanced rotor-bearing system under nonstationary random seismic excitation;

Equations of motion of a rotating machinery system for calculating its vibration response to seismic excitation is established by using a beam model with Coriolis effects taken into account when the base is subjected to an earthquake excitation with rotational components.

Performance of variable dampers for vibration control of structures under seismic excitations is investigat.

Seismic response analysis of a long-span cable-stayed bridge under random seismic excitations with spatial variations,including travelling effect, incoherence effect and local site effect, was made with stochastic method.

Although it has been demonstrated that as two typical examples of conventional semiactive control systems,active variable stiffness(AVS) and active variable damper(AVD) may be effective for vibration control of buildings subjected to seismic excitations,the latest research results show that obvious deficiencies still exist in both of them.
