Abstract
Compressive experimental behavior of lightweight fiber reinforced concrete
combined with traditional transverse steel reinforcement consisting in steel
spirals was analyzed. Lightweight aggregates were utilized to give lightness to
the composite, and steel hooked fibers were added to the matrices besides the
traditional steel lateral reinforcement to increase the ductility of members in
compression. The investigation was carried out through compressive tests on
cylindrical specimens, by imposing monotonic or cyclic displacements and
recording the full load-deformation curves. Empirical stress-strain equations were
adopted to reproduce with a good level of approximation the actual behavior of
cylindrical specimens under uniaxial co
