HERA R4-134: Semi-rigid joints for moment resisting steel framed seismic resisting systems

Description

This thesis report describes the development of new semi-rigid joints for moment-resisting steel framed (MRSF) seismic-resisting systems. Intended as the weak link in the seismic-resisting system, in accordance with a strong column, weak joint philosophy, the joints and systems were designed and detailed to withstand the design level ultimate limit state (500 year return period) earthquake with minimum damage. To meet economic criteria, the joints and systems were also required to be cost-effective to design, fabricate and construct when compared with conventional MRSFs.
