Structural steel elliptical hollow sections

项目摘要

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.

结构椭圆空心部分代表了结构工程师可用的横截面范围的最新补充。但是，尽管基于建筑吸引力和结构效率，对其应用的普遍兴趣，但缺乏经过验证的设计指南仍在抑制吸收。拟议的项目旨在通过一系列经过统计验证的设计规则来克服这一目标，该规则是基于合理的理论理解，精心进行的实验室测试和复杂的数值建模而开发的。实验室测试将是生成所需基本数据的关键工具，一旦经过校准，数值建模将用于研究单个参数的重要性并扩展可用数据的范围。设计规则将考虑到结构工程师，并仔细考虑在结果的准确性和易于计算方法之间找到适当的平衡。所有新的设计指南将根据欧洲框架框架制定，目的是将其考虑纳入法规的未来修订中。将调查结果传播给学术界将通过期刊出版物和国际会议的介绍进行。这是伦敦帝国学院与利兹大学之间的共同应用，利用了申请人的综合经验和设施 - 帝国大学的加德纳博士（Gardner）博士与无效的钢铁钢铁和富有史无章的Converies and Conforts of Confortise and Contection of Conforties and Contection of Conforce and Contection of Conforce and Contection of Conforce and Contression frows of the Importability College and Collectional and Contression Conformise and Contection。
