Global Behavior Factor of Frames with Eccentric Bracings and Relationships with the Ductility Requirements

Article Preview

Abstract:

During alternate loading cycles, as during earthquakes, the structure behavior becomes inelastic. This is particularly the case for steel structures. They show a better ability to absorb earthquake energy. This energy dissipating capacity is described by the q global behavior factor as used in the Eurocode 8. However, in other earthquake codes, it is expressed by R letter and in others only the X and V shapes bracing systems are taken into account in the seismic design. In this work, a method for determining the global q behavior factor is presented for eccentrically braced steel frames that are designed to resist seismic loads.
