Abstract

Abstract

Test investigation was performed on the stainless steel flexural members with sections consist of SHS,RHS and welding H section.The flexural members were made in austenitic stainless steel type 304. The test included 39 flexural members totally with 11differernt size sections.The test demonstrated that the simply supported SHS and RHS beams mainly have three different failure modes with different constraint to web and different load methods: flexural failure,web crippling and the combination of flexural failure and web crippling.On the other hand,the beams with welding H-sections were liable to flexural-torsional buckling.Then the test results were compared to the results obtained by EN1993-1-4 and SEI/ASCE 8-02 in the following aspects: the flexural capacity,the nonlinear deflection and the stability coefficient of the welding H-beam.These comparisons indicate that: test results of flexural strength and flexural-torsional buckling strength were higher than those predictions using above design codes; deflections predicted using above design codes were smaller than tests results．
