The hybrid-steel concrete connection for seismic behaviour
was studied using the numerical models. Finite element
analysis was employed as a numerical tool to investigate
the behaviour of joints. Concrete was modelled using 2D
elements, whereas truss elements are employed for steel bars.
The connection plates are modelled as 2D elements with steel
properties and the DIANA software was used as the modelling
tool. Comparisons with the experimental results indicated that
the finite element models used in this study were suitable,
and the corresponding investigation results were reliable.
The predicted results matched well with the experimental
observations. The connection plate modelled using 2D plate
elements and neglecting the concrete on either side of it showed
a satisfactory performance in the structural analysis. Based on
the parametric study results, the following conclusions can be
drawn
