A. Plasticity.
Plastic behaviour and plastic collapse. Collapse of beams: plastic hinges, ultimate moment for symmetric and non-symmetric cross-sections. Elasto-plastic evolution of framed structures. Collapse mechanisms.
B. Stability.
Basic concepts; equilibrium of the deformed configuration. Stability of frames with one-degree of freedom. Euler beam; Euler critical load, effective length, slenderness, stability design.
