A concrete frame is a popular type of construction that consists of a network of columns and connecting beams that constitute a building's structural "skeleton." This grid of beams and columns is often built on a concrete base and serves to support the building's floors, roof, walls, cladding, and other components. The beams are usually made of steel or timber, but wood frames can be used instead. The columns are typically made of reinforced concrete, although metal columns are now being used more frequently due to their durability and cost-effectiveness. In addition to providing structural support, the concrete frame also acts as the floor and roof framing for the building. The exterior wall surfaces may be finished in brick, stone, paneling, or some other material. The interior of the building is divided into rooms by using sheet metal or wood trusses to span from one beam to another. The trusses connect together at their ends to form a triangular shape if you count each leg of the truss as one piece. They are then covered with plywood or similar materials to create ceiling and wall surfaces. The advantages of using a concrete frame structure include its strength and stability, which makes it suitable for high-density building applications. It can also provide relatively inexpensive housing due to its simple design and lack of moving parts.
