Abstract

This experimental investigation was aimed at gathering information on the flexural properties, including ductility, of high-strength lightweight concrete members(concrete with a dry unit weight of approximately 1.85t/$\textrm{m}^3$ and with compressive strength approaching 630kg/$\textrm{cm}^2$ at 56days) under reversed cyclic loading. Two sets of six specimens each were manufactured using lightweght aggregate concrete having compressive strength of 350kg/$\textrm{cm}^2$ at 28days and 630kg/$\textrm{cm}^2$ at 56days. The test variables were the concrete strength, the amount of longitudinal reinforcement, and the spacing of ties. The test results, including hysteretic load-deflection curves, for the specimens representing columns under zero axial load are reported in this paper.
