Abstract:

The seismic random vibration responses of shear beam structures with uncertainty are investigated. The structural mass and stiffness are considered as random variables. The excitations adopted are stationary or non-stationary random process ground accelerations in horizontal direction. Using the structural random response in frequency domain, the mean square seismic random displacements of shear beam structures are expressed as the function of random structural parameters. Computational expressions for the mean value and standard deviation of structural seismic random response are then developed by means of the random variable's functional moment method. The effects of the randomness of structural parameters on the structural random responses are demonstrated by an engineering example. © KSME & Springer 2010.
