This study presents the structural properties of oil
palm shell kenaf fibre Lightweight concrete (OPS-
KFLC) beams. The main objective of this research
was to investigate the potential advantage of kenaf
fiber for improving the structure properties of OPS-RC
beams. This investigation carried out by two methods
experimental and consequently numerical modelling.
The experimental work focused on two beams. First
beam constructed with full shear reinforcement and
without fibre (SI = 0% and with Vf = 0%) denoted as a
control beam. Meanwhile one more beams with full shear
reinforcement (SI = 0%) and with fibre volume fraction
of Vf = 1% constructed respectively. The experimental
work has been considered four point flexural tests on
simply supported beam. Consequently, numerical
modelling with finite element method FEM software
Abaqus for calibration and validation of experiment
results considered. First, sensitivity analysis (mesh
and time) conducted up to acquire the best correlation
with experimental result. Then, the experiments result
of beams was used, for calibration in FEM modelling
investigation. The results comparison showed that
there is a good agreement between the experimental
test and nonlinear finite element analysis NLFEA
results. Generally, this investigation demonstrated up
to 37% improvement on structure properties of OPS-RC
beam by addition of Vf = 2%kenaf fiber.
