Abstract

d
shapes, ferrocement had been seen as a possible alternative to traditional construction materials.
In this research, the behavior of ferrocement composites tanks under static pressure loads was
investigated experimentally and numerically. The investigational work includes testing twelve
ferrocement composites circular tanks with dimensions 400mm outer diameters, 500mm height,
and 25mm thicknesses. The tanks are reinforced with welded and expanded steel meshes, as well
as glass fiber mesh. According to the findings of the experiments, the ferrocement composites
tanks have a higher failure load than traditional RC tanks, especially tanks reinforced with
fiberglass polymer-mesh. The tank reinforced with three layers of Fiberglass polymers-mesh has
the greatest first crack and ultimate load, as well as the highest ductility ratio and energy
absorption. The non-corrosive fiberglass reinforcement mesh offers several advantages over
structural steel meshes. In addition to its corrosion resistance, it boasts a significantly higher tensile
strength (up to twice as high), is extremely lightweight, is non-conductive, and has very low
thermal conductivity. The experimental results are compared to analytical models using (ANSYS
ver. 16.2) software. The finite element simulations generated better results than the experimental
data. The consistency ratio between the NLFEA and experimental results (Pu NLFEA/Pu exp.)
was found to be outstanding, with an average of 0.902 and a standard deviation of 0.024. The
correlation between the load-deflection curves of the NLFEA and experimental results was also
found to be appropriate, with a mean correlation of 88%. Furthermore, the matching ratio between
the NLFEA and experimental results (∆u NLFEA/∆u exp.) was found to be high, with a mean
matching ratio of 0.929 for all samples and a variation of 0.022. These results indicate that the
NLFEA model accurately anticipates the performance of the investigated samples, making it a
useful tool for predicting the behavior of similar structures. Ferrocement composite tanks have
several advantages over traditional reinforced concrete (RC) tanks, including increased strength of
up to 70% when using ferrocement composites, resistance to cracking, cost-effectiveness, and
resistance to corrosive substances. Finite element analysis (FEA) accurately predicts the behavior
of ferrocement composite tanks, enabling engineers to design and optimize these tanks more
efficiently. These advantages make ferrocement composite tanks a suitable option for various
industrial and developing country applications, especially when cost and strength are crucial
factors.Keywords: Ferrocement Composites; Expanded-steel-mesh; Welded-steel-mesh; Fiberglass-mesh;
