The use of elastic foundation model to analyze local tension distribution in the wall of steel built-up beams

Local tension in the walls of steel built-up beams is under movable load of the supported cranes. The level of the tension determines fatigue strength and durability of the construction. For the beams used hard working conditions of crane operation (7K, 8K) additional fatigue strength check of the upper zone of the wall of welded beams is required in accordance with design regulations.
