Analysis of the benefit of studs in steel-plate–concrete walls with bending and shear

An analytical study using non-linear finite-element modelling was conducted to evaluate the capacity improvement of adding studs between the concrete and steel plates in a steel-plate–concrete wall subjected to bending and shear. Non-linearity of the contact, connection details and material properties were considered when modelling the wall. The size of the model was determined through a literature review and by referring to code requirements. The model outputs compared well with the results of a laboratory experiment conducted in an earlier study. Different types and arrangements of studs were modelled to check they met Kepic-SNG criteria, the relevant design standard. After reviewing bending moment and buckling strength requirements, the optimum type and arrangement of studs were determined.
