摘要
不锈钢-混凝土-钢中空夹层组合管作为一种新型构件,可用作水下输送管道、框架柱、桥墩柱等。这种新型结构形式充分的利用了钢与混凝土两种材料的优势。本文借鉴钢-混凝土组合结构构件的基本假定,利用等效截面换算法将有效宽度内圆环形截面等效成工字型截面,简化了计算过程及复杂性,并为组合截面研究提供计算依据。
Stainless steel-concrete-steel hollow sandwich composite pipe can be used for underwater pipelines, frame columns, bridge pier and other column as a new type of structure. This new structure can make full use of the advantages of the two materials steel and concrete. This paper used for reference the basic assumption of steel-concrete composite structure. Using the equivalent cross section conversion method translate an equivalent circular cross section of the effective width to I-shaped cross-section. It simplifies the complexity of calculations and processes, and provides the basis for the research of the combination section.
