摘要 The Zhijiang River Bridge was used as a test model to study the mechanical behavior of long-span arch-shaped steel tower cable-stayed bridge. The test model was designed and simulated with a finite element method,which was confirmed to reflect the actual behavior of a structure. An experimental model was assembled, and a load test was performed under four conditions. The test results of the stress of the main tower and the deformation of the main beam were analyzed, and the working condition of the maximum bending moment in the middle span was used as an example. Results showed that the measured data and the converted value of the actual results of bridge calculation were relatively close. The actual structure had high safety reserves. Our research provided a reference for similar bridge and test model designs.

Abstract：The Zhijiang River Bridge was used as a test model to study the mechanical behavior of long-span arch-shaped steel tower cable-stayed bridge. The test model was designed and simulated with a finite element method,which was confirmed to reflect the actual behavior of a structure. An experimental model was assembled, and a load test was performed under four conditions. The test results of the stress of the main tower and the deformation of the main beam were analyzed, and the working condition of the maximum bending moment in the middle span was used as an example. Results showed that the measured data and the converted value of the actual results of bridge calculation were relatively close. The actual structure had high safety reserves. Our research provided a reference for similar bridge and test model designs.
