| Abstract: | Based on some special study results and international review reports in the preliminary design of Su-Tong cable-stayed bridge, which is at present the largest cable-stayed bridge in the world with a main span of 1 018 m, a detailed comparison study on global static stability under some critical load cases is presented, including how to determine the variable instability loads, fundamental instability rules and some comments which mostly may be regarded as the current research subjects in this field. |

| Keywords: | cable-stayed bridge static stability geometric nonlinearity material nonlinearity superlarge span |
