A nonlinear stochastic optimal (NSO) control strategy for wind-excited tall buildings is proposed. The power spectral density (PSD) matrix of the fluctuating part of wind velocity vector is diagonalized in eigenvector space. Each element of the diagonalized PSD matrix is modeled as a set of second-o
