Design and Numerical Analysis of Gusset Plate Connections in Compression

Popis výsledku v původním jazyce

This paper investigates the compressive resistance of gusset plate connections, focusing on single-sided bracing configurations with eccentric load. A total of twelve full-scale tests were performed on CHS bracing members connected via gusset and cleat plates using bolted joints. The specimens varied in gusset plate thickness, steel grade, and connection geometry. Two modelling approaches were applied using the Component-Based Finite Element Method (CBFEM): a simplified joint-level model and a detailed member-level model based on GMNIA, incorporating geometric and material nonlinearities as well as initial imperfections. The numerical results were compared with experimental data, and imperfection amplitudes were selected in accordance with prEN 1993-1-14. The findings confirm that the simplified model provides conservative estimates, while the GMNIA-based model offers improved accuracy and better alignment with experimental results, particularly when asymmetric imperfection shapes are considered. The paper highlights the key parameters influencing compressive resistance and supports further refinement of predictive methods for gusset plate connections.
