Model Test and Finite Element Analysis for the Pylon of the Jointed Pylon Cable-Stayed Bridge

Abstract:

In order to roundly investigate the whole structural behavior of the jointed pylon of cable-stayed bridge, 3:40 scaled-down model test and space finite element analysis （FEA） were presented by taking Yongjiang super-large bridge as an example. Test objective, model design principle, the ratio of similarity, test cases, loading method and the strain test point arrangement were introduced in detail. By comparison of two unfavorable cases, most test data were quite agreeable with the theoretical data, which verified the design concept. The results indicate that the whole resistant behavior is well and the structure is safe and reliable. FEA which is conducted using commercial program ANSYS is a reliable method for predicting the complex stress distribution in the jointed pylon structure.
