NUMERICAL STABILITY OF IVERSE ALGORITHM OF SUCCESSIVE FORMULA METHOD FOR DYNAMIC RESPONSE·ANALYSIS

It is discusssed that the numerical stability of iverse algorithm of successive formula method for dynamic response analysis in equal time interval case. The results show that the iverse formula of the relative acceleration is instable, the one of the absolute acceleration or the relative displacement is conditionally stable, and the relative velocity is unconditionally stable. It is discussed on preliminary application problems of the algorithm in the end of the paper.
