Abstract: The invention relates to a prefabricated panel for light-weight one-way joist slabs of the compound section type, comprising an upper contributing layer, a lower contributing layer having a series of upper peaks and troughs and shear transfer bolts which secure the upper contributing sheet to the upper peaks of the lower contributing sheet, and shear bolts or pins which secure the lower contributing layers to the slab framework beam.

Abstract: The present application relates to reinforced concrete columns classed in the category of reinforced concrete according to the NSR-10 and ACI-318 standards, in which the tubular channel is formed by sections with cold-roll sheets (CR) which form C-sections with a core and at least on skid which projects into the inner space of the column, coming into contact with the concrete. The skid comprises along its length a series of perforations through which concrete can pass, allowing a composite column to be formed once the concrete has set, in which steel and concrete work together and mutually strengthen their qualities to such an extent that the thickness of the sheet can be reduced, rendering the product economically viable. Moreover, the invention relates to the composite deck comprising these C-sections and a concrete core confined in the inner space of the tubular channel.
