Railway Bridge CAD Software Program
After analyzing the features of all kinds of CAD software program, this paper reaches such a conclusion: most of traditional bridge-design programs focus on calculating structural load, so nowadays the calculating feature of this software programs is greatly improved. At the same time, a common problem is still with traditional bridge-design software programs, and this problem is all this programs don’t have any model that offer information referred to the bridge being designed, and this problem result in isolation of data in different stage of designing. To solve this problem, this paper proposes that railway bridge CAD software program take ACCESS as core database and AUTOCAD as supporting graphical system, and we should develop new software program on this basis. This paper also propose that bridge-design software program we develop in future should take design knowledge and bridge information referred to 3D geometric data in consideration, so that the design software program can reuse the characteristic component databases and all kinds of information in different design stage.
