Finite Element Model for End-Plate Beam-to-Column Connections Under Bending and Axial Forces
Resumen
The assessment of steel beam-to-column connections is a fundamental piece in the design process of steel structures according to the guidelines established by standards such as Eurocode 3—Part 1.8 and ANSI/AISC 358-16. In addition, the finite element analysis is an alternative path to determine the behavior of steel beam-to-column connections in contrast to the analytical methods. Furthermore, the axial force in a semi-rigid steel structure connection is usually negligible compared to a bending force. However, there are some scenarios where the influence of axial forces cannot be ignored due to their elevated value. Therefore, a finite element model for end-plate beam-to-column connections is proposed considering the actions of bending and axial forces. The numerical simulation results were validated with experimental data, and an approximate representation of the physical phenomena was obtained.
