Abstract

Tests are reported to determine the uniaxial compressive stress-strain curves of lightweight aggregate concrete including the descending portion of the curve. The effect of lateral confinement and compressive strength on ductility are evaluated. It is shown that an essentially elasto-plastic response for lightweight concrete could be obtained by providing a large amount of confinement. The results are compared with those of normal weight concrete.
