betonskeletten

Betonskeletten, or reinforced concrete skeletons, are a structural system in which a frame of reinforced concrete columns and beams carries most of the loads, while walls primarily serve as non-structural partitions. The floor slabs are integrated into the frame, forming a three-dimensional skeleton that transfers loads to foundations. This leaves interior spaces free from heavy load-bearing walls, enabling flexible layouts.

Construction typically uses reinforced concrete with steel reinforcement bars or prestressed strands. Connections between columns, beams, and slabs are designed to transfer bending moments and shear forces. In some cases, elements are precast and assembled on site, or post-tensioning is used to improve performance and reduce slab depth. The system is well suited for varieties of buildings, from residences to office towers, and can incorporate fire safety and acoustic performance through material choices.

Historically, reinforced concrete skeletons gained prominence in the early to mid-20th century with the rise of modernist architecture. They enabled larger spans, open floor plans, and taller buildings than traditional masonry. The method remains common worldwide and is widely used in both new construction and renovations, including high-rise offices, residential towers, and parking structures.

Advantages of betonskeletten include design flexibility, good fire resistance, durability, and efficient material use for tall buildings and long spans. Challenges involve the need for precise formwork and workmanship, potential cracking if not properly designed and cured, and considerations for seismic or wind loads. Modern practice continues to optimize materials, such as high-strength concrete and post-tensioning, to enhance performance and sustainability.
