The main purpose of the current study is to investigate the effect of openings existence on the structural behavior of ferrocement I –beams with two different types of reinforcing metallic and non-metallic meshes. Eight beams are tested under a four-point loading system until failure. The beams are divided into two groups according to the type of meshes used as reinforcement. Each group contains a control I-beam with no openings and three beams with one, two, and three openings. To keep a constant reinforcement ratio, the two groups are, respectively, reinforced with three layers of welded steel meshes and two layers of tensar meshes. It was observed that beams reinforced with welded steel meshes showed a higher ultimate load, deflection, ductility ratio, and energy absorption compared to beams reinforced with tensar meshes. In addition, beams with three openings showed a lower ultimate load, deflection, ductility ratio, energy absorption, and load-to-weight ratio than the other beams with the same type of reinforcing meshes.
