Seismic behaviour of innovative joints of steel frame structures

In recent decades, great attention has been paid in the field of steel structures to the development of innovative structural beam-to-column joints that improve the behaviour of structures under seismic action. The innovation of joints with dampers lies not only in the control of the location of energy dissipation, but also in the possibility to easily replace them. The paper provides a concept for the behaviour of innovative joints with seismic dampers and summarises the state of the art, focusing on the development of a marketable concept for such joints.
