| Abstract: | Applying the concept of "strong support frame theory" in Article 5.3.3 of the Code for Design of Steel Structures(GB 50017—2003),referring to relevant literatures,and combining with the structural characteristics of steel trestles in the port engineering,we adopt the a combination of truss and single column structure for the large-span and high-support trestle.The practical method for determining the column length is proposed. |

| Keywords: | strong bracing frame lateral rigidity trestle effective length coefficient |
