| Abstract |
To improve the efficiency of structural design process for large-scale structures, distributed structural algorithms for efficient structural analysis of large-scale structures including high-rise building on the network of personal computers called PARASOL-I and PARASOL-II have been developed by the authors.
In this paper, a distributed algorithm for structural analysis of large-scale space structures called PARASOL-3DT is developed and presented. In the distributed structural analysis model, multi-level substructuring techniques are used for load balancing on the slave computers. The computational model has been implemented on a network of personal computers connected by the Ethernet network. The algorithm is applied to analysis of three space truss structures including 120-story envelop structure with 26136 degrees of freedom. |
