| Abstract: | In this paper, the accuracy and stability of some numerical integration algorithms in pseudodynamic testing are analyzed in detail. The analysis result shows that the modified Newmark method has better accuracy and stability, and in particular, its numerical damp can restrain the error growth. It is an ideal numerical integration method in Pseudodynamic testing of multiple-degree-of-freedom system. |
