Abstract
This research aims to developing the structural behavior of ferrocement beams with opening. To accomplish this
objective, an extensive experimental program was conducted. In addition, theoretical mathematical calculations were investigated. The experimental program comprised casting and testing of twelve reinforced concrete beams having the dimensions of 100x200x2000mm and 1900mm clear span. The main variable were (the number of openings, the type of steel meshes(expanded steel meshes and welded steel meshes) the number of meshes).
The experimental results showed that high ductility and good energy absorption properties could be achieved by using the proposed beams the test results of the currrent experimental program showed that the deveoped ferrocement beams with openings and reinforced with welded steel mesh and expanded steel mesh achieved high strength, better deformation characteristics, crack resistance, high ductility and energy absorption properties. Irrespective of the type and number of steel mesh layers and number of openings, they had better mechanical properties the convventional reinforced concrete beams. The results also demonstrated
that ferrocement concrete beams with openings showed fine crack widths at failure without spalling of concrete weight could be achieved by utilizing welded galvanized steel mesh, expanded metal mesh and polypropylene fibers for durability reason.
