The Flexural Capacity of 7A04-T6 Aluminum Alloy Rectangular Hollow Section Beams
This paper presents a particular experimental research on rectangular hollow section (RHS) and square hollow section (SHS) beams made of 7A04-T6 aluminum alloys. A total of 18 in-plane bending specimens four-point configurations have been investigated. The influence of length, cross-section slenderness was investigated. Full load–rotation and load–displacement histories were derived, containing into the post-ultimate stage. Material parameters of each member was acquired from tensile experiments. The experimental results were duplicated by means of non-linear numerical modelling. Based on careful validation of the models, a total of 96 parametric studies were performed to assess the structural response of RHS/SHS over a wider range of cross-section slenderness. Following analysis of the data, the correctness of the flexural capacity provisions in the present design specifications EN 1999-1-1 (Europe) and GB 50429 (China) was assessed. The results showed that the design rules provided conservative predictions of the ultimate flexural capacities. In this study, modified design rules based on Eurocode 9 (Europe) are proposed, which are shown to improve the accuracy of these design rules in a reliable manner.
