摘要
应用GB 50017—2003《钢结构设计规范》5.3.3条"强支撑框架理论"概念,结合港口工程中钢结构栈桥支柱结构特点,对大跨度、高支架的栈桥采用组合桁架与单柱结构,提出合理确定该结构体系中柱计算长度的实用、简捷方法。
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.
