Title
Post-impact fire resistence of t-stub joint component:numerical evaluation
Current paper presents a finite element analyses for the characterization of the nonlinear
behaviour of bolted t-stub component subject to impact loading followed by fire. The proposed
numerical model has previously validated against experimental results under monotonic static
loading at ambient and elevated temperatures (Ribeiro et al., 2013). 3D solid and contact elements
from the finite element package Abaqus are used to perform the structural model. The temperature
dependent material properties, the geometrical and material nonlinearities (including the strain rate
sensitivity) were taken into account to predict the failure of the t-stub. A parametric study was
conducted to to provide insight into the overall behavior, namely their stiffness, resistance, ductility
and failure modes due to the effects of dynamic loading followed by fire.
