In recent years, large-scale numerical analysis in structural design are increasingly demanded because of the necessity of realizing dynamic response analysis with elastic plastic behaviors in large-scale space frame structures. In order to realize large-scale numerical analysis, the developments of new high performance computing system without super-computers are desired. In several approaches, a parallel computing system is especially gathering the most attention for engineers. Thus the purpose of this study is to develop a parallel processing system for the dynamic analysis by using a PC cluster, which is a group of personal computers connected to a network mutually. Furthermore the calculating ability of the system is investigated by the numerical experiments for single layer lattice domes in this paper. It is demonstrated that the iteration method proposed to the dynamic analysis for structures is suitable for parallel calculations. Accordingly it was found through numerical experiments that the ability of parallel computing in this system produce good results and that parallel calculations using PC cluster with four personal computers reduce total analysis times to about 54% for models with different number of freedoms.
