| Abstract: | This paper derives a closed form solution for stationary random seismic response of long span structures considering wave passage effect. Based on the solution, the influence of the wave passage effect on response of long span structure are discussed by numerical examples. It is shown that the wave passage effect may have significant effects on responses of long span structures and should be taken into account in practical engineering. |
