Abstract
Moment resisting frames and braced frames are both being used extensively as lateral force resisting systems in multi-storey buildings nowadays. While moment resisting frames are known for being ductile, the eccentrically braced frame alternatives provide increasing stiffness but reduced ductility while retaining high energy dissipation capacity. The thesis focusses primarily on the possibility of combining the two systems (MRF and EBF) in order to achieve the best of both worlds (an increased initial stiffness and high energy dissipation at moderate earthquakes with enough reserve ductility for severe earthquakes). This ensures non-collapse of structures at severe ground displacements with easy repair and rehabilitation measures at frequent less severe seismic demands.
