Monotonic and cyclic behaviour of lightweight concrete beams with and without steel fiber reinforcement

摘要

Experimental tests on four lightweight concrete beams with and without steel fiber reinforcement, subjected to monotonic and reverse cyclic loads, were set-up in order to investigate the influence of the fiber reinforcement on the strength, ductility and energy dissipation. The tests were performed on beams with 200 x 300 mm cross section and clear span of 3000 mm. Furthermore, in the framework of the definition of sustainable materials, the cement of the concrete matrix was partially substituted by ashes coming from the combustion of Municipal Solid Waste (MSW), with pozzolanic reaction. The obtained results are presented, discussed and compared. (C) 2016 Elsevier Ltd. All rights reserved.
