Based on the analysis of a space elasticplastic timehistory procedure EPDA,the aseismatic behavior of a space frame structure in high earthquake intensity zone under seldom occurred earthquake is studied with timehistory analysis method.

A new design method which can be applied to the built up arch structure with RC piles for deep excavation is presented,which is executed by the analysis of space frame.

The computation analyses are shown by two practical examples that the computation errors will be greater when the space frame foundations under the action of Turbodynamos and electromotor are simplified to plane frame founations.
