| Abstract: | A model test on the anchorage-box of the Second Nanjing Changjiang River Bridge was conducted at the Center of Structural Engineering Experiment of Southwest Jiaotong Universiy. The safety of and the detailed stress distribution in this structure, and the reliability of the connection between the anchorage-box and webs are investigated. The test results are practically in agreement with those of FEM calculation and are recommended as references for designs of similar structures. |
