摘要

基于对圆形和方形两种截面的双层钢管混凝土构件的研究结果，研究了一种在轴向和循环荷载作用下的新型八边形和多边形截面钢管混凝土构件。为此，外钢壁具有各种钢形状，内钢壁与圆形截面相同，在某些分析中，外管与圆形截面一样，内壁具有各种钢截面。首先，通过一些现有的试验研究对有限元程序进行了验证，然后对七根不同截面类型的组合柱进行了分析。分析结果表明，在循环荷载作用下，所提出的钢截面的强度有所提高，磁滞性能有所改善。

BEHAVIOR OF CFDST COLUMNS WITH OCTAGON AND POLYGON STEEL SECTIONS

Based on some findings on the two kinds of Concrete Filled Double Skin steel Tube (CFDST) members with circular or square sections, a new kind of CFDST with octagonal and polygonal section have been investigated under axial and cyclic loading. For this purpose, the outer steel wall has various steel shapes and the inner steel wall is the same as circular section and for some part of analyses, the outer tube is the same as circular section and the inner wall has various steel sections. Primarily, FEM procedure has been verified with some available experimental studies and then, seven composite columns with different section types have been analyzed. The results of analyses exhibited the increase in strength and improvement in hysteresis behavior of the proposed steel sections under cyclic loading.

期刊介绍： Journal of Urban and Environmental Engineering (JUEE) provides a forum for original papers and for the exchange of information and views on significant developments in urban and environmental engineering worldwide. The scope of the journal includes: (a) Water Resources and Waste Management [...] (b) Constructions and Environment[...] (c) Urban Design[...] (d) Transportation Engineering[...] The Editors welcome original papers, scientific notes and discussions, in English, in those and related topics. All papers submitted to the Journal are peer reviewed by an international panel of Associate Editors and other experts. Authors are encouraged to suggest potential referees with their submission. Authors will have to confirm that the work, or any part of it, has not been published before and is not presently being considered for publication elsewhere.
