Finite element calculation of redesigned welded joint at support for frame stage‐like structure
Apstrakt
A numerical analysis of welded connection between two steel structures is performed with the usage of the finite element approach. A frame stage‐like structure is placed between the main horizontal girders of the structure of the hall. A visual inspection of the frame revealed numerous irregularities of welds which brought demand for redesign and overall check. The emphasis in this paper is comparative calculation of initial and redesigned welded end‐joints, without imposing the optimal technical solution. It is used modern and particular finite element software for calculation of welded joints. The values of stresses in the welded joint as well in plates and members are lower than the permitted values for both models. However, the influence on the main structure is reduced with redesigned technical solution. The level of stresses is lower along with reduction of rotational stiffness of the joint. This can be considered as a relief to the main girders of the hall structure and should b...e a cost and a goal for supporting any additional structure.
