Square and rectangular hollow sections under transverse end-bearing force

This paper describes tests on a range of cold-formed square and rectangular. hollow secti.on members subject to end-bearing force. The concentrated force was apphed by means of a beanng plate, which acted across the full flange width of the section. The parameters vaned In the tests Included (1) the beanng length; (2) the slenderness of the member; and (3) the shape of the section [rectangular hollow sections (RHS) or square hollow sections (SHS)]. The results are compared with existIng American, Australian, Canadian, and European design formulas. The results are also compared wIth the formulas given by the. writers, which were based on tests of SHS and RHS sections under interior bearing force. A design model is proposed for SHS and RHS sections under end-bearing force. The reliability analysis method is used to calibrate the existing and proposed design formulas.
