椭圆形空心截面（EHS）的结构性能已在以前的研究中进行了检查，在孤立的纯压缩和纯弯曲载荷条件下。本文探讨了EHS下的组合压缩加单轴弯曲的横截面水平的响应。结构性能数据最初是通过一系列具有各种荷载偏心率的实验室短柱试验产生的。本文报告了测试样本的测量几何和材料特性以及完整的载荷-变形历史。通过并行数值研究产生的进一步结果补充了测试数据。在分析工作之后，开发了在组合压缩加弯曲下EHS的细长参数和极限。最后，使用实验和数值数据来验证组合载荷下EHS设计的拟议相互作用表达式;这些表达式是根据欧洲规范3开发的，以便将来合并。
The structural behaviour of elliptical hollow sections (EHS) has been examined in previous studies under the isolated loading conditions of pure compression and pure bending. This paper examines the response of EHS under combined compression plus uniaxial bending at the cross-sectional level. Structural performance data were initially generated through a series of laboratory stub column tests with various load eccentricities. The measured geometric and material properties of the test specimens, together with the full load-deformation histories have been reported herein. The test data were supplemented by further results generated through parallel numerical studies. Slenderness parameters and limits for EHS under combined compression plus bending were developed following analytical work. Finally, the experimental and numerical data were used to verify proposed interaction expressions for the design of EHS under combined loading; these have been developed in accordance with Eurocode 3 for ease of future incorporation.
