Improved beam, characterized essentially by the fact that it is constituted by a mixed set, integrated by a prestressed-reinforced concrete piece, and by steel stirrups embedded in the above-mentioned piece, the latter presenting a section of form derived from an isosceles trapezoid, whose vertices relative to the adjacent equal angles of the major base are truncated, the resulting lower edge being killed, and the oblique sides of the trapezoidal section providing an inclined support for the joists.
