Steel reinforced concrete column

A steel reinforced concrete column for a high rise building comprising:

• a plurality of hot-rolled steel sections extending longitudinally through the concrete column, each of these steel sections having an outward flange with an outer surface turned outwards in the concrete column, an opposite inward flange with an outer surface turned inwards in the concrete column, and a central web connecting the outward flange to the inward flange;
• wherein:
• the steel sections are arranged in the concrete column so that the outer surfaces of their inward flanges delimit therein a central concrete core with n lateral sides and a transversal cross-section that forms an n-sided polygon, n being at least equal to three, each of the n lateral sides of the central concrete core being coplanar with the outer surface of the inward flange of at least one steel section;
• and
• the steel reinforced concrete column has a longitudinal axis along which the steel sections extend, so that the longitudinal axis of each steel section is parallel to the longitudinal axis of the steel reinforced concrete column.
