Numerical evaluation of the hysteretic performance of pure aluminium shear panels

The current paper deals with a numerical investigation on the use of pure aluminium shear panels to be used as effective passive control devices of new and existing buildings. Based on the implementation of a sophisticated FEM model, which has been calibrated on the basis of previous experimental tests, a wide numerical analysis has been carried out considering panels with different rib configurations, aiming at emphasizing the influence of the main behavioural parameters on the dissipative capacity of the system. In particular, numerical cyclic analyses have been carried out considering different displacement demand levels, comparing the performance of shear panels characterised by different rib depths. Finally, economical considerations about the most suitable configuration to be adopted in relation to the estimated displacement demand have been drawn.
