摘要：The pseudo excitation method (PEM) is extended to the analysis of wind-excited random vibration (buffeting) of complex structures. The partial correlation between wind excitations and the cross-correlation terms between the participant modes have all been involved in the computations. The proposed method is not only accurate, but also very efficient, e.g. structures with thousands of degrees of freedom can be computed very quickly on ordinary personal computers. A large shipyard crane is taken as a case Study of the method.
