ABSTRACT:
A joist suitable for use in a composite concrete floor is disclosed. The joist comprises a top chord, a bottom chord; and a vertically extending intermediate web having a top end secured to the top chord and a bottom end secured to the bottom chord. The top chord comprises a pair of longitudinally continuous symmetrical chord members facing each other and embracing the top end of the web. Each of the chord members includes a vertical portion secured to the top end of the web and a slanting upper extension extending above and away from the top end of the web, thereby providing a shear connecting portion and a flared opening, between the two facing chord members, giving access to the web and improving access of a welding tool to the area between the symmetrical portion of the top chord and the web member that must be joined together.
