<p>PROBLEM TO BE SOLVED: To ensure the strength of a truss sufficiently by reducing eccentricity, in which the contacts and supporting points of the neutral axis of a horizontal member and the neutral axis of a diagonal member are displaced, as much as possible. SOLUTION: A horizontal member 1 consisting of channel steel and a diagonal member 2 composed of channel steel are arranged so that the openings of the grooves of the channel steel are faced oppositely while an end section in the longitudinal direction of the horizontal member 1 and the end section of the diagonal member 2 are joined. Accordingly, a reinforcing material 4 is installed at a place on the opening side of the groove of the channel steel in the longitudinal direction in at least one of the horizontal member 1 or the diagonal member 2. The place of a neutral axis is moved to the inside of a truss by mounting the reinforcing material 4, and the displacement of the contacts and supporting points of the neutral axes of the horizontal member 1 and the diagonal member 2 is reduced.</p> |
