| Abstract: | The bridge fabrication machine of ZQL32/64 medium span continuous beam is qualified for continuous curved beam construction. On curved section, both guide beam and main beam bear torsion moment, with complicated stress status. Torsion stress analysis was made of the machine by using ANSYS general finite element program, and computation and analysis were made of the five most dangerous working conditions during bridge construction. |
