Abstract

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 prop- erties 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 be- haviour and modelling of the dissipative braces are discussed. 1 Introduction In the conventional aseismic design it is accepted that structures can with- stand strong ground motions by mainly undergoing inelastic deformations. However, the structural damage is oft
