Frame Structure Bridge Design CAD Software Systems

摘要

After the railway speeding-up, a large number of railway level-crossing has changed to the underpass or overpass type of structure. In the underpass type of structure, the most of structure take the underpass bridges or frame bridge structure. This paper put forward the level-crossing rebuild into the frame structure bridge method of design, through using the object-oriented program design method realizes the frame structure bridge automatic design analysis, calculation and drawing process, greatly enhancing the frame structure bridge design work efficiency, accelerating the changing level crossing to grade rate, and eliminating the safety trouble of crossings.
