Improved semi-resistant joist, characterized in that it constitutes a rectangular parallelepiped beam having its two lower longitudinal edges determined by respective bevels forming two lower lateral ramps inclined inwards, which give rise to the creation of grooves on the underside of the panel forming several beams, so that the furrows fill the layer of construction material that covers that lower face grabbing better to it, said stringer constituting the beam has recessed the longitudinal central strip of its upper face in the determination of a channel, which does not exceed in depth the level of the beginning of the bevels, filling the concrete of the slab that is set on the construction site on the beam to ensure the grip of the floor to it.
