“…The determination of such characteristics requires a complete understanding of the behaviour of single components, as well as of the way in which they interact, as a function of the geometrical and mechanical factors of the complete connections, Nethercot & Zandonini (1989). Wales & Rossow (1983) practically introduced the use of mechanical models, or rather, a component-based method, when they developed a model for double web cleat connections, Fig. 1, in which the joint was idealised as two rigid bars connected by a homogeneous continuum of independent nonlinear springs.…”
