Reinforced concrete frames are structural systems used in buildings and other constructions. They consist of vertical columns and horizontal beams made of concrete, which is strengthened with steel bars or mesh. This combination allows the structure to withstand various forces, such as gravity and wind, making it durable and stable. The use of reinforced concrete frames is common in modern architecture due to their versatility and cost-effectiveness. They can be designed to accommodate different architectural styles and are often used in high-rise buildings, bridges, and parking garages. This method enhances the overall strength and longevity of the structure.
