Karmirakenteiden

Karmirakenteiden, meaning "frame structures" in Finnish, refers to a type of construction method where buildings are erected using a skeleton or frame made of load-bearing elements. These elements, typically made of wood, steel, or reinforced concrete, form the primary structure that supports the floors, walls, and roof. The infill materials, such as bricks, panels, or glass, are then used to enclose the space but do not bear the main structural load. This approach allows for greater design flexibility and often faster construction times compared to traditional load-bearing wall systems.

The concept of frame structures has evolved over centuries, with early examples utilizing timber framing. The development of steel and reinforced concrete in the 19th and 20th centuries significantly expanded the possibilities, enabling the construction of taller and more complex buildings. In modern construction, steel frames are common for high-rise buildings and industrial structures due to their strength and ability to span large distances. Reinforced concrete frames are also widely used, offering durability and fire resistance. Timber frames continue to be a popular choice for residential buildings and smaller commercial structures, valued for their sustainability and aesthetic qualities. The distinct advantage of karmirakenteiden lies in its ability to separate the structural support from the exterior cladding, offering architectural freedom and efficient use of materials.
