The Development Of CAD System For City Prestressed Concrete Continuous Bridge

Today, the prompt development of software and hardware technology gives us the advantage to develop a new generational bridge CAD system. According to the speedy development of software technology and the state of the bridge CAD application, the thesis studies completely on the exploration technology of bridge CAD system. The main research content include: the limitation of the extant analysis system;modern technology which can be used in the bridge CAD system exploration;the necessity and viability of the integrated bridge CAD system.To extenuate the sufferings of designers from boring and tedious drawing work, take the need of the real world into consideration, and as a part of the mentioned integrated bridge CAD system, this paper realized the function to draw the structure and the steel picture on the basis of using VC++6. 0 and object-oriented language .By all of this , the paper makes some theory preparation for the later work.
