Abstract:
Lightwieght concrete in a structure is always a reinforced material. This investigation therefore focused on reinforced rather than plain lightweight concrete and looked at the descending portion of the stress-strain curve as a measure of ductility. Factors that influence the ductility and cost of lightweight structural columns are confinement and the characteristics of the steel and concrete. Columns were designed and priced; it was concluded that it is economically feasible to increase the amount of confinement in order to increase the ductility of lightweight members.
