    Abstract
  • Storage requirements of precise integration method were discussed.Series solution of the method suits dynamic response analysis of large-scale structures much better than other methods.Parallel computing of series solution has been researched and implemented.Time integration of precise integration method includes two items.The first item was computed serially and the second item was computed in parallel.Then a corresponding flowchart was given.Load distributed strategies were discussed for the parallel algorithm.The unbalanced distribution of time steps was implemented.The strategy can decrease the waiting time of the initial value for each processor.The final example shows that parallel algorithm of series solution has high speedup.
