| Résumé | Upgrading non-code conforming buildings to mitigate seismic induced damages is important in moderate to high seismic hazard regions. The damage, however, can be mitigated by using conventional (e.g. FRP wrapping) and emerging (e.g. smart structures) retrofit techniques. A model for the structure to be retrofitted should include relevant performance indicators. This paper proposes a variable stiffness smart structure device known as the Smart Spring to be integrated on building structures to mitigate seismic induced damage. The variable stiffness capability is of importance to structures that exhibit vertical (e.g. soft storey) irregularities and to meet different performance levels under seismic excitation. To demonstrate the utility of the new retrofitting technique, a four storey steel building is modeled in MATLAB and appropriate performance indicators are chosen. Various return period seismic hazards are generated from past earthquake event records to accurately predict the structure's performance. The performance improvement due to the retrofitting of building structures using the variable stiffness device is presented. |
