The seismic response of single-degr

The seismic response of single-degree-of-freedom (SDOF) systems incorporating ag-shaped hysteretic structural behaviour, with self-centring capability, is investigated numerically. For a SDOF system with a given initial period and strength level, the ag-shaped hysteretic behaviour is fully dened by a post-yielding stiness parameter and an energy-dissipation parameter. A comprehensive parametric study was conducted to determine the in uence of these parameters on SDOF structural response, in terms of displacement ductility, absolute acceleration and absorbed energy. This parametric study was conducted using an ensemble of 20 historical earthquake records corresponding to ordinary ground motions having a probability of exceedence of 10% in 50 years, in California. The responses of the ag-shaped hysteretic SDOF systems are compared against the responses of similar bilinear elasto-plastic hysteretic SDOF systems. In this study the elasto-plastic hysteretic SDOF systems are assigned parameters representative of steel moment resisting frames (MRFs) with post-Northridge welded beam-to-column connections. In turn, the ag-shaped hysteretic SDOF systems are representative of steel MRFs with newly proposed
post-tensioned energy-dissipating connections. Building structures with initial periods ranging from 0.1 to 2 : 0s and having various strength levels are considered. It is shown that a ag-shaped hysteretic SDOF system of equal or lesser strength can always be found to match or better the response of an elasto- plastic hysteretic SDOF system in terms of displacement ductility and without incurring any residual drift from the seismic event.
