Data Pre-define Storage of collaborative Bridge Design System

The dataflow of an bridge design system is tightly coupled with expensive numerical computation. This is one of the main reasons for the lack of a generic purpose data management system for collaborative design system. In the effort of trying to alleviate some of the problems, we have introduced a pre-definition approach for data storage of collaborative design system. The main design principle of the system is to define data storage based on design knowledge, so that only the need data is stored during design process. Firstly, based on the analysis of bridge design system in data storage, a model for data representation of collaborative design system is presented. Secondly, two kinds of data pre-define storage mode including interactive mode and knowledge-based mode are studied. Lastly, pre-define model of data storage is validated through an bridge project.
