Structural steel elliptical hollow sections

结构椭圆空心截面代表了结构工程师可用的截面范围的最新增加。然而，尽管在建筑吸引力和结构效率的基础上对它们的应用产生了广泛的兴趣，但缺乏经过验证的设计指导正在抑制吸收。拟议项目旨在通过生成经过统计验证的设计规则来克服这一问题，这些规则是在良好的理论理解、仔细进行的实验室测试和复杂的数值建模的基础上开发的。实验室测试将是生成所需基本数据的关键工具，一旦校准，将使用数值模型来调查各个参数的重要性，并扩大现有数据的范围。设计规则将与结构工程师一起制定，并仔细考虑在结果的准确性和计算方法的易用性之间找到适当的平衡。所有新的设计指南都将根据欧洲规范框架制定，目的是考虑将这项工作纳入该规范的未来修订版。将通过期刊出版物和在国际会议上发表报告向学术界传播研究结果。这是伦敦帝国理工学院和利兹大学的联合申请，利用申请人的综合经验和设施-来自帝国理工学院的Gardner博士，在钢管和不锈钢元件的不稳定性方面具有专长，以及利兹大学的Lam博士，他们在连接和混凝土填充复合管方面具有专业知识。

Structural elliptical hollow sections represent a recent addition to the range of cross-sections available to structural engineers. However, despite widespread interest in their application on the basis of both architectural appeal and structural efficiency, a lack of verified design guidance is inhibiting uptake. The proposed project aims to overcome this through the generation of statistically validated design rules, developed on the basis of a sound theoretical understanding, carefully conducted laboratory tests and sophisticated numerical modelling. Laboratory testing will be the key instrument for the generation of the fundamental data required, and once calibrated, numerical modelling will be used to investigate the importance of the individual parameters and to extend the range of available data. Design rules will be developed with structural engineers in mind, with careful consideration given to finding the right balance between accuracy of result and ease of calculation method. All new design guidance will be developed in line with the Eurocode framework, with the aim that the work may be considered for incorporation into future revisions of the Code. Dissemination of the findings to the academic community will be made through journal publications and by presentation at International conferences.This is a joint application between Imperial College London and the University of Leeds, making use of the combined experience and facilities of the applicants - Dr Gardner from Imperial College with expertise of the instability of tubular steel and stainless steel elements, and Dr Lam from the University of Leeds with expertise of connections and concrete filled composite tubes.
