管状结构是现代建筑的代名词。管状截面的熟悉范围正方形，矩形和圆形空心截面-最近已扩展到包括椭圆形空心截面（EHS）。由于围绕两个主轴的弯曲刚度不同，这些新型截面联合收割机将圆形空心截面的优雅与矩形空心截面弯曲时改进的结构效率相结合。在引入结构钢EHS之后，对其结构响应进行了大量调查。本文介绍了一个国家的最先进的审查最近的研究EHS连同一个样本的实际应用。本文论述了弹性局部屈曲和后屈曲、截面分类、剪切响应、构件失稳、连接和混凝土填充的EHS的行为等基础研究。详细的全面测试和数值模拟研究进行了说明，并产生统计验证的结构设计规则，适合纳入国际设计规范，概述。
Tubular construction is synonymous with modern architecture. The familiar range of tubular sections square, rectangular and circular hollow sections - has been recently extended to include elliptical hollow sections (EHSs). Due to differing flexural rigidities about the two principal axes, these new sections combine the elegance of circular hollow sections with the improved structural efficiency in bending of rectangular hollow sections. Following the introduction of structural steel EHSs, a number of investigations into their structural response have been carried out. This paper presents a state-of-the-art review of recent research on EHSs together with a sample of practical applications. The paper addresses fundamental research on elastic local buckling and post-buckling, cross-section classification, response in shear, member instabilities, connections and the behaviour of concrete-filled EHSs. Details of full-scale testing and numerical modelling studies are described, and the generation of statistically validated structural design rules, suitable for incorporation into international design codes, is outlined.
