Identification of crack width behavior of one-way reinforced concrete slab structure at different steel reinforcement area

An evaluation study of crack limit states based on design codes and prior research is presented in this publication. Its main goal is to connect research findings to common design codes. Researchers continue to face a difficult dilemma when it comes to reinforced concrete structure fractures, particularly in one-way slab constructions where there is still significant damage and corrosion in the reinforcement because of cracks. Practitioners will find it easier to construct these structures and solve the slab durability issue if the proper formula is discovered. One can overcome reinforced concrete. A method for estimating the maximum fracture width formula in one-way reinforced concrete slabs with varying steel areas is suggested based on this research. Slabs use a variety of steel areas, including 1000 mm2, 1200 mm2, and 1400 mm2.The test specimens are the same length of 2 meters and have a slab width of 0.6 meters with steel reinforcement. Findings from a literature review of research codes and prediction formulas from earlier studies, namely wmax(prop)=1.5*10-2fsAs-0.4, indicate that the maximum crack width is not significantly influenced by steel area (As). Overall, the findings from the two methods used in this analysis match the suggested formula and the observed experimental testing. This data indicates that the maximum fracture width has been greatly lowered by increasing the steel Area (As) of the reinforced concrete slab, leading to the determination of the experimental formula, As a result, a unique approximation formula has been developed to assess the impact of steel area parameters for pure slabs on the maximum crack width formula for one-way reinforced concrete slabs. This crack width formula is only applicable to one-way slabs in practice.
