Title: C-SECTIONS AND COMPOSITE DECKS FORMED BY COLD-FORMED SHEETS FOR A SYSTEM OF COMPOSITE REINFORCED CONCRETE COLUMNS
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 (1) and at least one skid (2) which projects into the inner space of the column, coming into contact with the concrete (4). The skid (2) comprises along its length a series of perforations (3) 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.
