Seismic design of non-structural components mounted on irregular reinforced concrete buildings

The seismic response of non-structural components (NSCs) attached to irregular reinforced concrete (RC) multi-storey buildings is underestimated by current European design provisions. This paper presents a new model for NSCs, accounting the effect torsion and capacity an RC primary structure (P-structure). proposed modification Eurocode 8 (EC8) acceleration amplification factor NSCs. It based on results some 5000 nonlinear dynamic finite element analyses conducted thirty-three building cases. covered wide range parameters including plan layout, capacity, fundamental vibration period, total height, floor rotation, ground type eccentricity ratio. has been demonstrated be improvement over EC8 model, especially NSCs mounted flexible side in tune with period P-structure.
