RESUMO

This work presents a numerical and experimental analysis on the structural behavior of bolted beam-column extended end plate connections. The behavior of the end plate and bolts used in the calculations of the end plate strength is specially discussed. Numerical results are used as basis to the discussions presented in this work and the modeling methodology, with FE models built with the ANSYS code, included 3D models of extended end plate and T-stub connections. The beam-to-column load transfer mechanisms and the yielding mechanisms at end plates and bolts are observed using numerical and experimental results. The yielding lines at the end plate are evaluated against the methodology proposed by Eurocode 3 for the calculations on the equivalent T-stub. Regarding the aforementioned factors, it is shown that the collapse modes indicated by Eurocode 3 do not represent satisfactorily the behavior of the analyzed connections. The numerical modeling was found to be general in application and reliable as a tool for parametric analyses and as a complement to experiments
