Fast Algorithm for Stationary Stochastic Response Subjected to Multi-component Multi-support Seismic Excitation

  • To calculate the stationary stochastic response of a long-span bridge subjected to multi-component and multi-support seismic excitation,a pseudo-excitation method was proposed based on the single-component pseudo-excitation method.Theoretic analyses show that this pseudo-excitation method has the same accuracy as the classic stochastic vibration method,but calculation rate of the former is 10 times faster than that of the latter,and the traveling wave effect and partial correlation effect can be included easily.
