  • Recently the construction of residential buildings faces many difficulties due to the shortage of building materials and works. Simplifying the stage of processing and assembling reinforcing rods and increasing the efficiency of them in reinforced concrete construction can be used to settle the difficulties. In the respect, structural wire-fabric and loop wire-fabric is utilized. The purpose of this study, on condition of being $210kg/cm^2$ concrete strength, is to analyze the structural and flexural properties of one-way concrete slabs by testing with different reinforcing type, tensile steel ratio based with minimum steel ratio, boundary condition and splice length which affect the maximum width of crack and ductility factor. From the test results, the ductility factor is approved that the slabs using deformed bar were much better than that using wire-fabric, and 30D of splice length was appropriate in the slabs as splice length. In the control of the maximum crack width the slabs using wire-fabric and loop wire-fabric were much better than that using deformed bar.
