摘要：Tubular sections have an excellent response under combined stress states.However, the use of this typology has been relatively recent, mainly due to the unfamiliarity in use.By filling them with concrete [composite sections] the two materials do not work only together, but they also improve their mechanical properties.This text points out the advantages of these sections and proposes the applicability of a new typology which goes beyond in structural optimization: hollow concrete-filled steel tubes.The hollowness in composite tubular sections improves their mechanical performance, and it also optimizes its behavior in case of slender columns.This paper pretends to divulge and encourage the use of these sections in new architectural designs, from the point of view of high-rise building and prefabrication.
