Behavior of Complex Hat Shape Cold-formed Steel Members

Abstract

The behavior of complex hat shape members used for both the top and bottom cord elements of a cold-formed steel truss was analyzed. A finite strip program was used as a means of determining the critical buckling mode. The ratio of critical buckling to the moment at yielding for hat sections provided good correlation graphically and analytically when compared with the Winter's and Hancock's curve for the series of beams with 2 ft. and 4 ft. load points apart. The results show that experimentally the combination of distortional buckling and overall buckling seems to have strong influences on the overall performance of the section.
