Abstract
For structures subjected to stationary or evolutionary white/colored random noise, their various response variances satisfy algebraic or differential Lyapunov equations. The solution of these Lyapunov equations used to be ver y difficult. A precise integration method is proposed in the present paper, which solves such Lyapunov equations accurately and very efficiently.
