This paper presents a numerical investigation on new box girder reinforced with various types of metallic and non-metallic mesh reinforcement materials. The main objective of the current numerical study is to estimate the structural behaviour of thin ferrocement box bridges reinforced with composite material. The numerical investigation has been studied a nine girders models. The dimensions of the girder were 2000 mm length, 500 mm width and 350 mm thickness but with various layers numbers made from different mesh types. Stresses and cracking patterns, tensile and compressive strains, deformation characteristics, ductility ratio, and energy absorption properties were observed and measured at all stages of loadings. Numerical results were captured by using (ABAQUS/Explicit) programs. The results showed that the type of reinforcement affects the ductility ratio, ultimate strength and energy absorption properties of the proposed girders. The study also revealed that the expanded metal mesh and welded steel mesh using in reinforcing the ferrocement girders are effective. Moreover, the developed ferrocement box girders have high ductility ratio, strength and energy absorption properties and are lighter in weight which are very useful for dynamic applications compared to the conventional RC girders, which could be useful for developed and developing countries alike. The Finite Element (FE) simulations achieved better results in comparison with the experimental results.
