Nonlinear Static Response of Low-Moderate Ductile Chevron Concentrically Braced Frames Designed According to Eurocode 8

Steel frames equipped with chevron bracing (?-CBF) are usually less ductile than other steel systems. Therefore, in many cases, it can be convenient to design ?-CBF exploit their stiffness and resistance enforce a pseudo-elastic seismic response of the building low moderate zones. In current EC8, rules for same as those high frames, thus potentially leading massive, over-resistant uneconomic next version EC8 new have been set ?-CBF, aiming enhance ease use code well obtain expensive structures. The updated based on local requirements elastic calculation without any plastic analysis. This paper discusses these that numerically investigated by means nonlinear static analyses 8-storey designed different intensities. performed show according exhibit ductility, preventing damage brace-intercepted beams reducing ductility demand braces under compression.
