Reinforced concrete beams are structural elements designed to support loads in buildings and bridges. They are made from a mixture of concrete and steel reinforcement bars, known as rebar, which enhances their strength and durability. The combination allows the beams to withstand tension and compression forces, making them ideal for various construction applications. These beams are typically used in floors, ceilings, and walls, providing stability and support. The concrete provides compressive strength, while the rebar offers tensile strength, allowing the beams to resist bending and cracking under heavy loads. This synergy makes reinforced concrete beams a popular choice in modern engineering.
