Collapse prevention and life safety are of utmost importance in Earthquake Resistant Design. Structures, however, still have a small probability of collapse due to uncertainties in the ground motion and the structure's response. The assessment of this probability requires the prediction, with sufficient confidence, of the structure's response through collapse and, thus, poses significant challenges. In order to validate those predictions and evaluate phenomena that are not adequately represented in component tests, experimental tests at the structure level are required. Shaking table tests, although an excellent option at first glance, can be very complex, expensive and even dangerous. Hybrid testing can be an attractive alternative since it can provide information of the response without having to test the entire structure, making it a versatile and cost-effective testing approach to the investigation of structures through collapse. The goals of this research are to conduct a comprehensive validation of hybrid simulation techniques to collapse, expand substructuring techniques used in distributed hybrid simulation to capture the effects of time-varying boundary condition and improve the capabilities and reliability of hybrid simulation by developing and incorporating adaptive analytical models.
