Concrete is reinforced by steel rebars, which act as tension members. When loads are applied to the concrete, such as the weight of a structure or external forces, it tends to crack and fail under tension. To counteract this weakness, steel rebars are embedded within the concrete.
Made of high-strength steel, the rebars have a much higher tensile strength than concrete. During the pouring of concrete, the rebars are strategically placed throughout the structure, typically in areas where tension forces are expected. These areas include beams, columns, and slabs.
As the concrete cures and hardens, it forms a strong bond with the steel rebars. When external forces are exerted on the concrete, like the weight of a building or lateral forces from wind or earthquakes, tension forces are generated within the concrete. However, instead of causing the concrete to crack and fail, the rebars bear the majority of the tension.
Due to the high tensile strength of the steel rebars, they can resist the tension forces, preventing the formation of cracks and ensuring the integrity and structure of the concrete. The rebars act as reinforcement by evenly distributing the tensile forces throughout the concrete, enhancing its overall strength and durability.
Moreover, rebars offer additional benefits to concrete structures. They can mitigate the effects of temperature changes, prevent shrinkage cracks, and enhance resistance to corrosion caused by environmental factors. In conclusion, the use of steel rebars significantly improves the structural integrity and lifespan of concrete, enabling it to withstand various loads and external forces over time.

When external forces are applied to the concrete, such as the weight of a building or lateral forces from wind or earthquakes, tension forces are generated within the concrete. However, instead of these forces causing the concrete to crack and fail, the rebars take on the majority of the tension.
The high tensile strength of the steel rebars allows them to resist the tension forces, preventing cracks from forming and ensuring that the concrete remains intact and structurally sound. The rebars act as a reinforcement by distributing the tensile forces more evenly throughout the concrete, enhancing its overall strength and durability.
Furthermore, rebars can also provide additional benefits to concrete structures. They can help minimize the effects of temperature changes, prevent shrinkage cracks, and improve the resistance to corrosion caused by exposure to environmental factors. Overall, the use of steel rebars in concrete construction significantly enhances the structural integrity and longevity of the concrete, ensuring its ability to withstand various loads and external forces over time.
Steel rebars provide reinforcement to concrete by adding strength and durability to the structure. When embedded within the concrete, rebars act as tension members, resisting forces that would otherwise cause cracking or failure. The high tensile strength of steel rebars helps to distribute and absorb load, enhancing the overall structural integrity of the concrete.
