Small And Medium-sized Road Bridges Cad System

Prestressed concrete voided slab in bridge superstructure, column pier in bridge substructure and bored pile foundation are widely used in a small and medium bridge on the road. But now they are designed by using bridge and culvert standard drawings and revising in AutoCAD manually. It spends much time of designers. In order to relieve designers from heavy drab computation and drawing, this paper developed 揝mall and Medium Bridge CAD System?based on Windows by analysing general structural design chart of slab small and medium bridge and obeying design custom of small and medium bridge. Using by VB5.O, ActiveX and object-oriented language, and conducting second exploitation on AutoCAD, the system realized drawing prestressed voided slab, bridge decking, column pier, post abutment, pile foundation, main bill of quantities ect.
