| Abstract: |
| Stationary response and first passage failure time of two classical hysteretic systems,bilinear hysteretic system and Bouc-Wen hysteretic system,are investigated by using Monte Carlo simulation method under non-Gaussian random excitation which consists of bounded noise,Poisson white noise and Gaussian white noise in the present paper.As bounded noise is a typical non-Gaussian random excitation with continuous sample functions and Poisson white noise is a typical non-Gaussian random excitation with discontinuous sample functions,different effects of parameters of these two non-Gaussian random excitations are investigated on probability densities of stationary response,probability densities and mean values of first passage failure time of bilinear hysteretic system and Bouc-Wen hysteretic system.It is found that probability density of first passage failure time of bilinear hysteretic system is a typical two-peak function,but which of Bouc-Wen hysteretic system is a one-peak function under such non-Gaussian random excitation. |
