Abstract

The compressive behavior of lightweight fiber reinforced concrete confined with transverse reinforcement consisting of steelstirrups or spirals was analyzed. Pumice stone and expanded clay aggregates were utilized to decrease the weight of the composite;hooked steel fibers were also added. The investigation was carried out by testing cylindrical and prismatic specimens of different sizesin compression using an open-loop displacement control machine, recording the full load–deformation curves. The influence of thedimensions and shape on the bearing capacity and on the ductility of the specimens confined with transverse steel reinforcementswas analyzed. The results show the possibility of obtaining high confinement level through the coupled effect of fibers and steeltransverse reinforcement.
