Abstract

The length of railway-highway combined bridge is large and it’s calculating model having many elements makes it need a great of manpower and time in the Finite Element Analysis (FEA). With redevelopment of ANSYS, a FEA program is empoldered so that complex load calculation and loads combination is worked out automatically in ANSYS. It reduces manpower, shortens time and improves work efficiency. the FEA program was used successfully in analysis of Zhengzhou Yellow River railway-highway combined bridge, and all the work of calculation and results processing can be finished in sixteen days, which saves much time in researching and designing bridge and obtains good social benefits and economic benefits. It also provides convenience for other analysis of railway-highway combined bridges and demonstrates idea for other similar questions of development of ANSYS.
