Research on software architecture of bridge CAD system

Architecture of engineering system can dominate software function and style. Selecting multiplayer architecture to sever as the principal part, Bridge Master, which consists of man-machine alternation layer, basic operations layer, application platform layer, function module layer and system management layer, is developed for bridge structure analysis. This paper analyzes the composition of the systematic structure to improve efficiency of engineering design and make designer using easier. On the basis of aforementioned analysis, the developer can strengthen systemic function on the aspect of individuation. Besides these, it also builds up the preliminary fundament based on which a new generational bridge integrated CAD system can be developed further.
