| Abstract: | An experimental study on the bearing of prestressed concrete beam for the light railway is carried out in the paper.The bearing is made of cast steel.The FEM method is used for studying static and fatigue strength analysis of the bearing of PC beams for light railway.A 3?D finite element is applied to model the bearing.The contact stress,Von Mises stress,and fatigue life of the bearing are computed.Static and fatigue tests are performed.The comparing results are shown that the computing results are well agreed with that of the test one.It is shown that the cast steel bearing has sufficient strength. |
| Keywords: | prestressed concrete beams bearing contract stress fattigue analysis |
