Title: Hybrid concrete structures - Experimental and numerical investigation of beams with lightweight concrete and fibre-reinforcement
Author(s): Linn Grepstad & Jan Arve Øverli
Appears on pages(s): 11-30
Keywords: Fibre-reinforced concrete, lightweight concrete, four-point bending test, finite element analysis
Abstract:Hybrid concrete beams of different size, consisting of a top layer of lightweight concrete and a 50mm bottom layer of fibre-reinforced concrete, were exposed to a four-point bending test . The beams were analysed numerically using the finite element code DIANA . Tests showed that the response for the small beams was dominated by one cracked zone and moment failures, while a distributed crack pattern was observed for the large beams where the ultimate capacity were governed by moment and shear failures. The numerical analyses were capable of simulating the global response of the beams.
