摘　　要：钢管组合柱结构作为一种竖向承重结构,被广泛运用于建筑结构体系。本文介绍了当前钢管组合柱主要组合类型及其偏心受压的力学特点,总结了国内外钢管组合柱结构的组合方式及偏心受压力学特点,分析了最新各种钢管组合柱结构的组合方式的优缺点及偏心受压研究现状,对薄壁方钢管砂卵石柱偏心受压承载力学性能研究的关键问题及未来的发展提出展望。With the development of the steel structure industry, China's steel output has ranked first in the world in recent years. The steel pipe combined column structure is widely used in the vertical load-bearing system of building structures. This paper introduces the combination type of the main steel pipe composite columns and the mechanical characteristics of the eccentric compression. It summarizes the combination of the domestic and foreign steel pipe composite column structure and the eccentric compression characteristics, and analyzes the combination of the latest various steel pipe composite column structures. The advantages and disadvantages of the research and the status quo of eccentric compression are presented. The prospects of the key issues and future development of research on eccentric compression mechanical properties of thin-walled square steel pipe sandy gravel column are put forward.
