THE CHAIRMAN, inviting discussion, said that the information given in the paper was of the type which was not found in text books, and that type of information was always most valuable.
The folowing simple graphical method for finding the stress distribution on a rectangle
loaded eccentrically about one axis only, has not been seen by the writer in any text book. Several methods ha,ve recently been described in "Engineering News Record," but the folowing method seems simpler than any.
With a little more latitude in headroom the upper laterals may be conveniently connected in the piane of the upper chord. Both struts and diabsnals consist, of four-angle members with lacing, Fig. 5. The diagonals intersect on a pair of horizontal gusset plates, and their axial lines should whenever possible intersect the axis of the main upper chords at 0. This sometimes entails larger gusset plates, but the advantage quite outweighs the cost of the slight amount of extra maherial required.
