Numerical modelling of gusset plate connections under eccentric compression

Popis výsledku v původním jazyce

Recently, new experimental study which was focused on behavior of bolted connections with gusset plate under eccentric compression was carried out at CTU in Prague. Buckling resistance and longitudinal and lateral deflection was measured for six specimens. The specimens represented full scale tubular bracing connected to rigid load-bearing construc-tion on both ends. Progressive 3D digital image correlation technology was used, to record planar strain of plates. This paper describes complex numerical models based on afore-mentioned physical specimens. General FEA software Abaqus including geometric and material nonlinearities (large deformations, plasticity, imperfections) was used. Numerical models were validated on results measured during experiments. Later, an extensive para-metric study was performed with nearly 50 numerical models. Influence of total of eight free parameters was examined. Besides other results, parametric study confirmed previous findings, that analytical models based on dispersion angle are generally not accurate for design of eccentric gusset plate connections.
