The seismic response of damped frames using different dissipative braces: a parametric study

A comparative study is carried out with reference to damped braced frames equipped with different kinds of dissipative devices. For this purpose the nonlinear seismic analysis of a single-degree-of-freedom system whose properties are suitably assumed to represent a damped braced frame is carried out. The effects produced by the dissipative braces on the ductility demand for the framed structure are evaluated assuming different properties of the frame members, braces and dissipative devices. Aspects concerning the behaviour and modelling of the dissipative braces are discussed.
