英文摘要	An extended precise integration method for computing the non-stationary response of a linear MDOF structure subjected to evolutionary random excitation was proposed. Random loads were firstly transformed into deterministic loads using a Pseudo-excitation algorithm before precise and efficient recursive relations with an unified form were constructed using the precise computing method of Duhamel integration. The avoidance of inverse matrix computing made the presented method independent to the nature of the system matrix or its dynamic matrices, enhanced the numerical stability and expanded its applied scopes. The presented method had the same high numerical precision as HPD-M and a higher efficiency than the dimension-expanded precise integration method. Examples were given to show advantages of this method.; EI; 0; 7; 131-134+142; 28
