Abstract

This study evaluates the behavior of the steel flush end plate (FEP) beam-to-column external joint, presented in reference [1]. The investigations involve both analytical and numerical approaches to assess the perfor mance of this typical connection. The analytical method, described in reference [2], represents the Com ponent Method and the numerical analyses involved two finite element method-based software, Consteel and IDEA StatiCa. These two software tools adopt two distinct methodologies - one utilizing the Component Method, while the other implements the Component-Based Finite Element Method. A comparative analysis of the results was performed to evaluate the reliability of the analytical and numerical methods and to analyse the differences between these procedures. The results of the investigations indicate that the end plate is the weakest component of the examined connection. Therefore, a numerical parametric study was conducted to analyse the influence of the end-plate thickness on the overall behavior of the steel flush end-plate beam-to column external joint.
