ABSTRACT
A lightweight concrete section has been developed with a novel use of prefabricated autoclaved
aerated concrete (AAC). This section, namely LSRC section, is a reinforced concrete section in
which AAC bricks are used as infill material. An experimental investigation into the strength of
LSRC beams has shown promising results under both flexural and shears tests. Based on the test
results, the flexural capacity was found to be almost identical to the capacity of the equivalent
solid beam,while the shear capacity was reduced. The shear strength reduction was as expected
due to the reduction in the compressive strength of AAC infill material. This paper focuses on
a numerical investigation into the behavior and strength of LSRC beams using ANSYS finite
element method of analysis. A numerical model is developed and the analytical results are
comparable with the experiment.
