| Abstract: | In this paper, the design methods of member under axially load in Chinese national standard ＂Code for design of aluminum structures＂ （ GB50429--2007 ）, ＂Technical specification for design and construction of aluminum-alloys reticulated structures＂ （ DGJ08 -95--2001 ） and ＂The Aluminum Association, Inc. Aluminum design manual＂ have been compared. This paper compared stability- factors of H-section 6061-T6 aluminum-alloy,obtained the local buckling stresses of H-section＇s flange and web,derived the relationship between overall member slenderness ratio and slenderness ratio of cross-section elements. Engineer should consider the overall stability, local stability and local buckling of axially loaded members simultaneously to find the most optimal section for aluminum structure. |
