Designing steel and composite structure in a low-to-moderate seismic area

Abstract

This contribution summarizes the results achieved in the frame of the research project MEAKADO funded by the European Commission. The goal of this project is to develop specific design procedures for steel and steel-concrete composite structures in regions characterised by a low to moderate seismic activity, aiming at an appropriate balance between safety level and economical concerns. The research program focuses on moment-resisting and concentrically braced frames. The targeted design methodology consists in providing the structures with limited but controlled ductility through structural requirements that are less stringent than designing according to Eurocode 8 – Ductility Class Medium principle, focusing on intermediate values of the behaviour factor.
