Topology optimization of structures under the action of fluctuating wind forces is considered.The wind forces are regarded as multipoint stationary random excitations.Compared with static analysis of structure,vibration analysis of wind-excited structures requires more computational efforts.Usually,the random response of wind-excited structures is computed in the frequency domain and the standard deviation of structural response can be evaluated through the numerical integration of its auto-spectral density function.To obtain higher accuracy of standard deviation,very small frequency intervals are needed for integration.Hence,such numerical integration is generally very time consuming and make it difficult to use in topology optimization.
