This thesis concerns the investigation of an actual steel folded plate roof and the resulting analysis. At the present stage of development, it appears that the folded plate could be used to form the roof system of many buildings at a savings of about 30% in weight of the steel when compared with standard bar joist construction. Speed of erection appears to favor the folded plate also, since the only welds required in the field are at the ends and along the lower fold line. While no particular difficulty was experienced in fabricating the test unit, it is well to emphasize that the type of welding does require some practice on the part of the operator. In summary, it appears that this light weight steel-folded plate structure has a tremendous potential for future roof spanning on this nature.
