Enter the random response of multi-phase structure


m + i, nc (k a 2mm) so the matrix of displacement response spectra of a {}'{} D s = [Zhu Zhu] around a group of heterogeneous transmission system r l + B (JB + BB.z) + ( BnB mouth of a B. l,] L (B, lB + B.1B) - i (ear lB a B1J) B + BJ root of shear as Q =. y from the spectral density of its population = Q'-Q S a f · ·, = V} (B + B chu) this small problem does not have to use mode superposition method, and continuous variables that directly seek answers.
