Abstract: Dealing with a stationary narrow-band Gaussian process X(t) with mean zero, this paper derives a number of approximate solutions on the basis of the point-process approach. In particular, upper ...

Abstract: The first-excursion probability of a stationary narrow-band Gaussian process with mean zero has been studied. Within the framework of point process approach, series approximations derived from the ...

Abstract: An exploratory study is made of the possible application of active control systems to tall buildings in along‐wind motion. An analytical procedure is developed to compute the statistical properties of the structural response ...

Abstract: A sensitivity study is conducted to investigate the effect of uncertainties in system identification on the performance of the active control system for seismic‐excited buildings. Four control algorithms feasible for ...

Abstract: A statistically-formulated fracture mechanics model for crack growth under sustained load is used to analyze crack growth data from 23 compact tension specimens of IN100, a turbojet engine disk ...

Abstract: The sensitivity of a system time delay with respect to the performance of control systems for seismic‐excited buildings is examined. The effect of a system time delay depends on the particular control algorithm and the ...

Abstract: An active mass driver has been designed for installation on the upper observation deck of the 310 m Nanjing TV transmission tower in China in order to reduce the acceleration response under strong wind gusts. In this paper, ...

Abstract: Optimal polynomial controllers have been proposed recently for applications to active/hybrid control of seismically excited structures. Such controllers have been demonstrated to be effective in limiting the peak dynamic ...
