摘要: This paper is the first part of an extensive work focusing technological development steel fiber reinforced concrete pipes (FRCP). Here presented and discussed experimental campaign test procedure mechanical behavior obtained for each dosages used. In second ("Steel pipes. Part 2: Numerical model to simulate crushing test"), aspects FRCP numerical modeling are analyzed using same results in order be validated. study was carried out trying reduce some uncertainties related performance provide a better condition use these components. this respect, sewage full scale as specimens. The diameter specimens 600 mm, they had length 2500 mm. were with traditional bars different contents fibers compare their through test. Two procedures used that sense. 1st Series, displacement monitored by two LVDTs positioned at both extremities 2nd just one LVDT spigot. shown more rigidity response pipe during tests when displacements measured enlarged section socket. reinforcement very effective, especially low level imposed FRCP. At condition, showed equivalent superior class made reinforced. content 40 kg/m3 provided hardening FRCP, could considered critical volume condition.
