This paper presents finite element analysis on Abaqus Software of a steel frame equipped with friction joints subjected to a static load and to a vehicle impact, in one of its external columns. The force-time histories were determined considering the loading patterns found on the experimental impact tests conducted on the joint and on the friction damper (Santos, et al. 2017).The behaviour of the friction joints was included in the model by a slot-rotation spring. For the impact analysis, the effect of high strain rates on the materials constitutive model. The numerical simulations are used to predict the structural robustness of a steel frame under exceptional loading conditions with the studied connections types. Furthermore, the behaviour of the frame with friction joints is compared with the behaviour of the same frame with rigid joints.

Abstract

This paper presents finite element analysis on Abaqus Software of a steel frame equipped with friction joints subjected to a static load and to a vehicle impact, in one of its external columns. The force-time histories were determined considering the loading patterns found on the experimental impact tests conducted on the joint and on the friction damper (Santos, et al. 2017).The behaviour of the friction joints was included in the model by a slot-rotation spring. For the impact analysis, the effect of high strain rates on the materials constitutive model. The numerical simulations are used to predict the structural robustness of a steel frame under exceptional loading conditions with the studied connections types. Furthermore, the behaviour of the frame with friction joints is compared with the behaviour of the same frame with rigid joints.
