Assessment of Capacity Design Approaches for Steel-Framed Structur

다국어 초록 (Multilingual Abstract)

This paper examines the underlying aproaches and main procedures adopted in the seismic design of stel frames, withconsiderations and capacity design verifications, are appraised. Focus is given to regular configurations of moment-resisting aswell as concentrically-braced frames. Several desirable practices incorporated in Eurocode 8, such as those related to theexplicit definitions and capacity design criteria for dissipative and non-disipative zones, are highlighted. On the other hand,important behavioural aspects that can lead to a departure from the intended capacity design objectives are discussed. Theseidealisations. In particular, it is shown that the implications of drift requirements in moment frames, and the distribution ofductility demand in braced frames, are issues that warrant cautious interpretation and consideration in the design process.
