Abstract
A test program on cold-formed steel channels subjected to concentrated bearing load is presented in this paper. The web slenderness values of the channel specimens ranged from comparatively stocky webs of 15.3 to relatively more slender webs of 62.7. The tests were performed under end and interior loading conditions. The test setup was different from the one specified in the North American Specification and the Australian/New Zealand Standard for cold-formed steel structures where the loading support is assumed free to rotate in the plane of the beam. The test specimens were seated on a fixed flat solid steel base plate, and a concentrated load was applied through a bearing plate to the top flange of the channels. The test setup simulates a floor joist member subjected to concentrated load. The test strengths are compared with the design strengths obtained using the North American Specification and the Australian/New Zealand Standard. It is concluded that the design strengths predicted by the North Americ...Keywords
