Semi-rigid Steel Beam-to-Column Connections
The article provides an analytical review of existing studies and design solutions of the beam-column joints in steel construction. The approaches to the study of the behavior of the beam-column joints of steel structures under static and cyclic dynamic loadings are reviewed. The existing methods for determining the stiffness are based mainly on regulatory engineering techniques, experimental and numerical studies. The methods are compared and the advantages and disadvantages of each are described. It is possible to achieve a reliable picture of the stress-strain state of joints in the elastic-plastic stage of work based on finite elements method. Because of large variety of joints, the further research remains relevant. The analysis of the applicability of the obtained characteristics, in particular moment-rotation diagrams, with the help of numerical calculation methods is carried out. Modern software based on FEM allows to use the obtained characteristics by different approaches of special zero-length rotational spring element. Computational power grows and so grows the skill of engineering modeling and calculation. However, the pinned and rigid joints concept is still remains basic in engineering practice; all the studies show that consideration of the flexibility of joints in the work of the frame is necessary and possible to process with the help of CAE programs.
