rakenneelementtimenetelmä

Rakenneelementtimenetelmä is a design method for structural engineering that involves the use of elements and systems to analyze and design the structure of buildings and other infrastructure. It is a holistic approach that considers the entire structure as a whole, rather than breaking it down into individual components.

The method was developed in the 1950s and 1960s by Finnish engineer Bengt G. Fellenius, who sought to create a more efficient and cost-effective way of designing structures. The method is based on the idea that the structure is a grid-like network of elements that work together to support loads and withstand external forces.

The rakenneelementtimenetelmä method involves several key steps, including the identification of the structure's load-carrying capacity, the calculation of the element forces, and the selection of suitable materials and construction methods. It also involves the use of mathematical models and computer simulations to analyze the behavior of the structure under different loading conditions.

The method has been widely adopted in Finland and other parts of Northern Europe, particularly in the design of bridges and high-rise buildings. It is known for its ability to handle complex loading conditions and its flexibility to accommodate changes in the design of the structure.

The rakenneelementtimenetelmä method has also been influenced by the development of other design methods, such as the finite element method and the structural analysis of safety. While it has its limitations, particularly when dealing with very complex structures, it remains a widely used and respected method in the field of structural engineering.
