Abstract
In this study, 10 ferroconcrete concrete (FC) beams with lightweight cores
reinforced with welded steel mesh as a shear reinforcement were evaluated
under three-point bending tests along with two conventionally normal
weight concrete (NWC) beams. Expanded polystyrene and lightweight
aerated autoclaved brick wastes were used to create lightweight core
concrete. The main factors include the type of lightweight concrete used
for the core, beam concrete type, the form and number of holes, the existing
steel mesh fabric, the hollow, and the hole placement. Study was done on
the tested beams’ ductility index, failure modes, first cracking loads and
associated deflections, and ultimate loads beside corresponding
deflections. Experimental results showed that use of FC, various filling
materials, and welded steel meshes in place of traditional stirrups enhanced
the ultimate load by 36.6-107.3%, the ultimate deflection by 6-272%, and
the ductility by 89-1155% referenced to a control NWC beam. When the
holing ratio increased from 10 to 20%, the ductility of FC beams was
enhanced by 307.7%. Proposed equations were developed to predict the
ultimate load and bending moment capacity of FC beams while taking into
account the compressive strength of the beam body and filling material, the
holing ratio, the tensile reinforcement ratio, and the volume fraction of the
steel mesh. In this research, analytical models based on the finite element
method (FEM) were studied, as ANSYS version 19.0 was used to study the
behavior of the tested beams until failure. The results of the developed
finite element models were compared with the test results, and a good
agreement was reached between the experimental and finite element
results.
